workqueue: un-GPL function delayed_work_timer_fn()

commit d8e794dfd51c368ed3f686b7f4172830b60ae47b ("workqueue: set
delayed_work->timer function on initialization") exports function
delayed_work_timer_fn() only for GPL modules. This makes delayed-works
unusable for non-GPL modules, because initialization macro now requires
GPL symbol. For example schedule_delayed_work() available for non-GPL.
