qcacmn: Avoid REO queue setup after peer deletion

REO queue setup is getting triggered from processing
pending null queue exceptions in WBM release ring, after
sending peer delete command to FW, but before peer unmap
is received, causing target assert. Mark peer deletion
before sending peer delete command to avoid this.
