qcacld-3.0: Serialize WMI_ROAM_EVENTID to MC thread

Browse source 
Currently WMI_ROAM_EVENTID is handled in work queue context whereas
WMI_ROAM_SYNCH_EVENTID is handled in MC Thread context. This can
cause handling of WMI_ROAM_SYNCH_EVENTID followed by WMI_ROAM_EVENTID
if both events are received from firmware almost at the same time
which can result in setting roaming_in_progress to true even after
roam synch event handling and can block further scan requests.
Fix this by handling both WMI_ROAM_EVENTID and WMI_ROAM_SYNCH_EVENTID
in same MC Thread context.
