qcacld-3.0: Handle ROAM_SYNC in RSO_STOPPED state

Browse Source 
Currently if Host receives ROAM SYNC event in
RSO STOPPED state, Host drops ROAM_SYNC event and
fails to send ROAM COMPLETE response to FW. This
results assert in fw with reason ROAM COMPLETE
response timeout.

If ROAM SYNC come to host in below scenario:
1. HOST sends RSO stop command with scan mode 4,
   in order to process supplicant disabled roaming
   request
2. FW already queued the roam sync event before
   RSO STOP command receive from host
In this case host should send RSO STOP with
scan mode = 0 to FW. So that FW can stop roam sync
timer and change roam state to RSO STOP state
along with other internal cleanup in FW.
