Currently the rx tid spinlock is destroyed from
peer delete (based on peer state) or peer unmap handler.
This can lead to a race condition when the peer is
deleted before the peer map command is processed/received.
Fix the above race condition by destroying the rx tid
spinlock only when the peer handle is destroyed/freed.
