If 2 MLO AP have same MLD addr, when roam between them, link vdev1 old
peer is deleted first, ML peer goes to state ML_PEER_DISCONN_INITIATED,
Since ML peer can be found for same MLD addr, no new ML peer is created,
but vdev1 new link peer is failed to attach to ML peer for wrong state,
then ML peer will be double freed, assert will happen.
To fix it, if roam target AP and current AP have same MLD addr, before
attach new peer to reused ML peer, update different info from target AP,
update ML peer state to ML_PEER_CREATED again.

For T2LM capable MLO STAs the AID is allocated from the second pool.
There is an inconsistency in allocating these AID pools.
Please check the example below.
Let's say the max_aid in ML AID manager is 12 and the start_aid is 3.
As per the current implementation,
aid_end1 = (ml_aid_mgr->max_aid - start_aid)/AID_NUM_BUCKET
= ( 12 - 3)/3 = 3
Only 3 AIDs are available in pool_1. But, all these 3 AID are reserved due
to start_aid = 3. Hence, we will not be able to allocate any AID from
pool_1.
With the fix,
pool_1_max_aid = (ml_aid_mgr->max_aid - start_aid)/AID_NUM_BUCKET
= 3
aid_end1 = pool_1_max_aid + start_aid
= 6
So for pool 1, AID 4,5 and 6 are available now.

true, since all link peers are attached to same PSOC.
But, FW and DP needs only one peer to be set primary.

This method causing issue since the order is not guaranteed
between FW and DP layer.
So, added a change to set is_primary to one of the link peers
