qcacld-3.0: Ignore deauth ind received when in DEAUTH_REQ substate

P2P GO received deauth frame from p2p client and del_station is
received from userspace. As part of del_station FORCE_DEAUTH_STA
command is processed. Deauth frame is processed after this which
sends DEAUTH_IND to csr. Wm status change command is enqueued and
is not processed since there is already an active command. Cleanup
is done as part of del_station. Auth frame received is processed
and auth rsp is sent. Message is posted to lim on receiving assoc
req frame from p2p client. Wm status change command is processed
and DEAUTH_CNF msg is posted to lim. Assoc req frame is processed
and ASSOC_CNF is posted to lim. DEAUTH_CNF is processed before
ASSOC_CNF due to which sta_ds entry is removed. Assoc resp is
not transmitted as a result and p2p group formation fails.

Fix is to ignore deauth indication received when csr substate
is DEAUTH_REQ.
