Roam_synch indication processing in host performs peer detach/attach
operations after firmware has already moved to the new peer. Out of
sequence peer unmap and map events can mess up the reference count
for reused peer_id values, which can lead to crash.
Solution:
While detaching a peer during roam sync indication processing,
copy its peer_id_ref_cnt in peer_id_to_obj array to new variable
in the same peer map for that peer id. Peer is deleted at that point.
When the unmap events come in, decrement the old ref_cnt and
map events increment the real ref_cnt.
Once the old ref_cnt goes to 0, subsequent unmap operations apply to
the real peer.
