When `zebra_evpn_mac_svi_add()` adds one found mac by
`zebra_evpn_mac_lookup()` and the found mac is without
svi flag, then call `zebra_evpn_mac_svi_add()` to create
one appropriate mac, but it will call `zebra_evpn_mac_lookup()`
the second time. So lookup twice, the procedure is redundant.
Just an optimization for it, make sure only lookup once.
Modify `zebra_evpn_mac_gw_macip_add()` to check the `macp`
parameter passed by caller, so it can distinguish whether
really need lookup or not.

Currently, `bgp_evpn_es_new()` always has an invald `struct bgp` pointer as
its input parameter, and it will always return valid `es`.
So two cleanup changes:
- Remove unnecessary checking for `bgp` in `bgp_evpn_es_new()`
- Remove unnecessary checkings of `bgp_evpn_es_new()`'s callers.

Modifying the code as per RFC 4604 section 2.2.1
EXCLUDE mode does not apply to SSM addresses, and an SSM-aware router
will ignore MODE_IS_EXCLUDE and CHANGE_TO_EXCLUDE_MODE requests in
the SSM range.
Issue is observed when a group in exclude mode was in ASM range
as per the prefix-list and then prefix-list is modified to make
it fall under SSM range. The (*,G) entry remains there.
So when the group moves to ssm range and it is exclude mode,
delete the group from the IGMP table.

Description:
Default route is not getting flushed from neighbours though originator
triggered flush and deleted LSA from its database. It become as stale
LSA in neighbours databse forever. This could seen in the following
sequence of configurations with less than a second interval b/w configs.
And this could happen only when originator shouldnt have default route
in its rib so it originates default route only when configure with 'always'
option.
step-1:default-information originate always
step-2:no default-information originate always
step-3:default-information originate
In step-1, default route will be originated to AS.
In step-2, default route will be flushed to AS, but neighbours will be
discarding this update due to minlsainterval condition.
And it is expected that DUT need to keep send this update
until it receives the ack from neighbours by adding each
neighbour's retransmission list.
In Step-3: It is deleting the lsas from nbr's retransmission list
by assuming it initiated the flush. This is cuasing to not
send the lsa update anymore to neighbours which makes
stale lsa in nbrs forever.
Fix:
Allowed to delete the lsa from retransmission list only when lsa is
not in maxage during flushing procedure.

When issuing a RTM_DELETE operation and the kernel tells
us that the route is already deleted, let's not complain
about the situation:
2022/03/19 02:40:34 ZEBRA: [EC 100663303] kernel_rtm: 2a10:cc42:1d51::/48: rtm_write() unexpectedly returned -4 for command RTM_DELETE
I can recreate this issue on freebsd by doing this:
a) create a route using sharpd
b) shutdown the nexthop's interface
c) remove the route using sharpd
This would also be true of pretty much any routing protocol's behavior.
Let's just not complain about the situation if a RTM_DELETE
operation is issued and FRR is told that the route does not
exist to delete.
