qcacmn: Not set "force_set" if event completed

"qdf_complete_wait_events" set force_set flag for all event in
"qdf_wait_event_list". This cause qdf_wait_for_event_completion
return QDF_STATUS_E_FAULT, even if event have completed

Add new flag "done" to record event completed. Use this flag to
detect event have completed or not.
