qcacld-3.0: Dont process SYNC IND if ROAM STOP cmd already posted to WMA

Browse source 
Currently, HOST sets discon_in_progress flag after posting
ROAM_SCAN_OFFLOAD_STOP command to WMA for a session. In case of
disconnection in HOST while roaming in FW if ROAM SYNC IND from fw comes
to host after posting ROAM_SCAN_OFFLOAD_STOP command to WMA, host start
processing SYNC IND and FW start processing ROAM_SCAN_OFFLOAD_STOP
which will cause to cleanup/disconnect with new AP to which it has just
roamed. After this cleanup fw will send HO_FAIL.

Now host as part of roam sync indication sends PEER_REORDER_QUEUE_SETUP
for the deleted peer which results in firmware assert.

Fix is to set discon_in_progress flag to true before posting
ROAM_SCAN_OFFLOAD_STOP command to WMA in order to ignore ROAM SYNC IND
and return status as failure to fw.
