ath11k: acquire ab->base_lock in unassign when finding the peer by addr
[ Upstream commit 2db80f9 ] ath11k_peer_find_by_addr states via lockdep that ab->base_lock must be held when calling that function in order to protect the list. All callers except ath11k_mac_op_unassign_vif_chanctx have that lock acquired when calling ath11k_peer_find_by_addr. That lock is also not transitively held by a path towards ath11k_mac_op_unassign_vif_chanctx. The solution is to acquire the lock when calling ath11k_peer_find_by_addr inside ath11k_mac_op_unassign_vif_chanctx. I am currently working on a static analyser to detect missing locks and this was a reported case. I manually verified the report by looking at the code, but I do not have real hardware so this is compile tested only.
