If CSR roam synch callback fails then the status is not updated
with error status code and this causes the caller to consider
roam synch indication is successful and RSO stop is not sent
to firmware leading to roam synch completion timeout at firmware
Send correct status to the caller of the api:
cm_roam_sync_event_handler_cb() if CSR roam synch processing
fails
