Ensures the correct calculation of `cfg_len` prior to the allocation of
the skb in the `rtw89_fw_h2c_scan_offload_be` function, particularly when
the `SCAN_OFFLOAD_BE_V0` firmware feature is enabled. It addresses an
issue where an incorrect skb size might be allocated due to a delayed
setting of `cfg_len`, potentially leading to memory inefficiencies.
By moving the conditional check and assignment of `cfg_len` before skb
allocation, the patch guarantees that `len`, which depends on `cfg_len`,
is accurately computed, ensuring proper skb size and preventing any
unnecessary memory reservation for firmware operations not supporting
beyond the `w8` member of the command data structure.
This correction helps to optimize memory usage and maintain consistent
behavior across different firmware versions.

When starting/proceeding MCC, it will abort an ongoing hw scan process.
In the proceeding cases, it unexpectedly tries to abort a non-exist hw
scan process. Then, a trace shown at the bottom will happen. This problem
is caused by a previous commit which changed some call sequence inside
rtw89_hw_scan_complete() to fix some coex problems. These changes lead
to our scanning flag was not cleared when proceeding MCC. To keep the
fixes on coex, and resolve the problem here, re-consider the related
call sequence.
The known sequence requirements are listed below.
* the old sequence:
A. notify coex
B. clear scanning flag
C. proceed chanctx
C-1. set channel
C-2. proceed MCC
(the problem: A needs to be after C-1)
* the current sequence:
C. proceed chanctx
C-1. set channel
C-2. proceed MCC
A. notify coex
B. clear scanning flag
(the problem: C-2 needs to be after B)
So, now let hw scan caller pass a callback to proceed chanctx if needed.
Then, the new sequence will be like the below.
C-1. set channel
A. notify coex
B. clear scanning flag
C-2. proceed MCC
The following is the kernel log for the problem in current sequence.

N.B. For cases of non-MLD connection, we set our link instance-0
active with link_id 0. So, our code flow can be compatible between
non-MLD connection and MLD connection.
Based on above, we tweak entire driver architecture first. But, we don't
dynamically enable multiple links here. That will be handled separately.
Most of the things changed here are changing flows to iterate all active
links and read bss_conf/link_sta data according to target link. And, for
cases of scan, ROC, WOW, we use instance-0 to deal with the request.
There are some things listed below, which work for now but need to extend
before multiple active links.
1. tx path
select suitable link instance among multiple active links
2. rx path
determine rx link by PPDU instead of always link instance-0
3. CAM
apply MLD pairwise key to any active links dynamically
Besides, PS code cannot easily work along with tweaking architecture. With

Each condition binding to the same wait should be unique. AOAC code misused
the wait of FW offload series and broke the above rule. It added another
macro to generate wait condition of WoWLAN/AOAC, but the results conflict
to the ones of FW offload series. It means that we might be completed
wrongly in logic. We don't want things work/read like this and should
have avoided this.
Fix this by adding another wait which aims for WoWLAN functions.

listed below which make us give up this plan after we know our Wi-Fi 7
HW design.
1. one link is bound to one HW band during its life time
but, one link might change chanctx dynamically
2. in concurrent mode, assume 1st vif is MLD
1st vif's 2nd link might use the same chanctx as 2nd vif
but, they are not on the same HW band
So, we let sub_entity_xxx stuffs deal with only chanctx now. And, to be

There is a length limit on the commands we send to firmware, so
dividing to two commands is sometimes required when scanning.
When aborting scan, we should not send second scan command to
firmware after the first one is finished. This could cause some
unexpected errors when we cannot receive firmware events
(e.g. in suspend).
Another case is scan happens before suspending, ieee80211_do_stop() is
called to abort scan and driver indicate scan completion by
ieee80211_scan_completed(), which queues event to scan work. But scan work
might be late to execute after ieee80211_do_stop(). To correct this, driver
indicates ieee80211_scan_completed() before returning, so that
ieee80211_do_stop() can flush scan work properly.

This adds support for hardware scan after FW version 0.34.35. Currently
we only support scanning on single hardware band and support of dual band
scan will be added in the future. Adjust the current flow to make driver
compatible with different generation ICs.

The channel field slightly differs between WiFi 6 and WiFi 7.
So we prepare some required functions in advance, this doesn't change
existing wifi 6 ICs behavior. This H2C prepares the channel list
to be scanned for. With layout as the following:
+--------+--------------------+-------------------+-----------------------+
| header | number of channels | channel info size | channel_info * number |
+--------+--------------------+-------------------+-----------------------+

This allows scan related logs when FW log debug mode is on.

When STA connects to an AP and doesn't receive any beacon yet, the
hardware scan is triggered. This scan begins with the default TSF
value. Once STA receives a beacon when switches back to the operating
channel, its TSF synchronizes with the AP. However, if there is a
significant difference in TSF values between the default value and
the synchronized value, it will cause firmware fail to trigger
interrupt, and the C2H won't be sent out. As a result, the scan
continues until a timeout occurs. To fix this issue, we disable TSF
synchronization during scanning to prevent drastic TSF changes, and
enable TSF synchronization after scan.

When aborting scan, wait until FW is done to keep both states aligned.
This prevents driver modifying channel then gets overwritten by FW.

When wpa_supplicant is initiated by users and not by NetworkManager,
the CQM configuration might not be set. Without this setting, ICs
with connection monitor handled by driver won't detect connection
loss. To fix this we prepare a default setting upon associated at
first, then update again if any is given later.

Use struct filling style instead of pointer casting.
This does not change the original behavior.

WiFi 7 chips will support MLD, so there are more fields about that. But
currently we don't support MLD yet, just define fields and bits by this
patch ahead, and fill STA_TYPE only.
