qcacld-3.0: Fix race between wpa_supplicant and scheduler_thread

Driver receives roam invoke command from supplicant, Host start
processing it in wpa_supplicant thread and sends ROAM_INVOKE
command to firmware. FW indicates roam invoke failure, so host
clean up the AP (Disconnect). But wpa_supplicant did not get
scheduled till disconnection completion. After disconnection,
wpa_supplicant thread gets resume and sets the roaming in progress
true. This results in roaming in progress remain set in a
disconnection state.
sme_fast_reassoc should be protected with sme lock to avoid
the race between SB disconnect and sme_fast_reassoc.

Fix is to protect sme_fast_reassoc with sme lock and
set roaming in progress flag before sending sme_fast_reassoc
command to FW and reset it again if sme_fast_reassoc fail to
initiate the roam invoke.
