Subject: [PATCH wq/for-3.19] workqueue: cosmetic update in rescuer_thread()

rescuer_thread() caches &rescuer->scheduled in a local variable
scheduled for convenience. There's one WARN_ON_ONCE() which was using
&rescuer->scheduled directly. Replace it with the local variable.

This patch causes no functional difference.
