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

[Tejun Heo]

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.
