workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending()
e0aecdd874 ("workqueue: use irqsafe timer for delayed_work") made try_to_grab_pending() safe to use from irq context but forgot to remove WARN_ON_ONCE(in_irq()). Remove it. Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Fengguang Wu <fengguang.wu@intel.com>
