SUMMARY: AddressSanitizer: heap-use-after-free zebra/rib.h:222 in re_list_const_first
This is happening because we are using the dest pointer after a call into
rib_gc_dest. In process_subq_route, we call rib_process() and if the
dest is deleted dest pointer is now garbage. We must reload the
dest pointer in this case.

When changing the peers sockunion structure the bgp->peer
list was not being updated properly. Since the peer's su
is being used for a sorted insert then the change of it requires
that the value be pulled out of the bgp->peer list and then
put back into as well.
Additionally ensure that the hash is always released on peer
deletion.
Lead to this from this decode in a address sanitizer run.

The list itself was not being cleaned up when the final list entry was
removed, so make sure we do that instead of leaking memory.

Memory leaks are observed in the cleanup code. When “no router bgp" is executed,
cleanup in that flow for aggregate-address command is not taken care.

This commit ensures proper cleanup by deleting the gm_join_list when a PIM interface is deleted. The gm_join_list was previously not being freed, causing a memory leak.
The ASan leak log for reference:

In the function ospf_lsa_translated_nssa_new the newly created lsa is lock however, the return lsa from ospf_lsa_new already has a lock. Therefore removing the addition lock resolve the leak below.

In scenarios where no backup paths are available, ensure proper
memory management by deleting `q_space->vertex_list`. This prevents
memory leaks.

This commit ensures proper cleanup by clearing the `algo->pdst` pointer if it points to a path that is being deleted.
It addresses memory leaks by freeing memory held by `algo->pdst` that might not have been released during the cleanup of processed paths.

When using "vtysh -f", the northbound compatible configuration is committed together whereas, in interactive mode, it committed line by line. In the first situation, in validation state nb_running_get_entry() fails because the area not yet in running. Do not use nb_running_get_entry() northbound validation state.
