workqueue: use irqsafe timer for delayed_work
Up to now, for delayed_works, try_to_grab_pending() couldn't be used from IRQ handlers because IRQs may happen while delayed_work_timer_fn() is in progress leading to indefinite -EAGAIN. This patch makes delayed_work use the new TIMER_IRQSAFE flag for delayed_work->timer. This makes try_to_grab_pending() and thus mod_delayed_work_on() safe to call from IRQ handlers.
