    workqueue: set delayed_work->timer function on initialization · d8e794df

    delayed_work->timer.function is currently initialized during
    queue_delayed_work_on().  Export delayed_work_timer_fn() and set
    delayed_work timer function during delayed_work initialization
    together with other fields.
    
    This ensures the timer function is always valid on an initialized
    delayed_work.  This is to help mod_delayed_work() implementation.
    
    To detect delayed_work users which diddle with the internal timer,
    trigger WARN if timer function doesn't match on queue.
