I think it is better to use cancel_delayed_work(), but change it to use
del_timer(). I belive cancel_delayed_work() doesn't need del_timer_sync().

We only care when del_timer() returns true. In that case, if the timer
function still runs (possible for single-threaded wqs), it has already
passed __queue_work().
