Subject: [PATCH] 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.
