Mike Galbraith 704f665920 workqueue: exit rescuer_thread() as TASK_RUNNING 
commit 412d32e6c9 upstream.

A rescue thread exiting TASK_INTERRUPTIBLE can lead to a task scheduling
off, never to be seen again.  In the case where this occurred, an exiting
thread hit reiserfs homebrew conditional resched while holding a mutex,
bringing the box to its knees.
