revert "cancel_delayed_work: use del_timer() instead of del_timer_sync()"
As pointed out by Jarek Poplawski, the patch [WORKQUEUE]: cancel_delayed_work: use del_timer() instead of del_timer_sync() commit: 071b6386 was wrong, it was merged by mistake after that. From the changelog: after this patch: ... delayed_work_timer_fn->__queue_work() in progress. The latter doesn't differ from the caller's POV, it does make a difference if the caller calls flush_workqueue() after cancel_delayed_work(), in that case flush_workqueue() can miss this work_struct.
