When the remote peer is neither EBGP nor confed, aspath is the
shadow copy of attr->aspath in bgp_packet_attribute(). Striping
AS4_PATH should not be done on the aspath directly, since
that would lead to bgpd core dump when unintern the attr.

Problem:
Execute the below commands, pim6d core happens.
interface ens193
ip address 69.0.0.2/24
ipv6 address 8000::1/120
ipv6 mld
ipv6 pim
We see crash only if the interface is not configured, and
we are executing PIM/MLD commands.
RootCause:
Interface ens193 is not configured. So, it will have
ifindex = 0 and mroute_vif_index = -1.
Currently, we don't enable MLD on an interface if
mroute_vif_index < 0. So, pim_ifp->MLD = NULL.
In the API pim_if_membership_refresh(), we are accessing
pim_ifp->MLD NULL pointer which leads to crash.
Fix:
Added NULL check before accessing pim_ifp->MLD pointer in
the API pim_if_membership_refresh().

This commit addresses a memory leak issue in the BGP Flowspec NLRI parsing function.
Previously when processing NLRI, dynamically allocated memory to `temp` was not being freed, leading to a memory leak.
The commit introduces the necessary code (XFREE) to properly free the temp memory after processing Flowspec NLRI.
The ASan leak log for reference:

On removal, ensure that the ifp->node is set to a null
pointer so that FRR does not use data after freed.
In addition ensure that the ifp->node exists before
attempting to free it.

the bgp_default_originate test brings up the topology and
then immediately pings. Which sometimes fails. This is
of course possible since the first ping might actually fail
due to arp going on. So let's give it a second chance or two.
Especially since the test, at this point, is just installing
a default route.

- Previously was substituting a pointer to local allocated session for the
session_id returned from the FE adapter. This complexity isn't needed.
- Get rid of "%llu" format and the casts that came with it, instead use PRIu64
and the actual (uint64_t) type.
