workqueue: wake regular worker if need_more_worker() when rescuer leave the pool
We don't need to wake up regular worker when nr_running==1, so need_more_worker() is sufficient here. And need_more_worker() gives us better readability due to the name of "keep_working()" implies the rescuer should keep working now but the rescuer is actually leaving.
