[PATCH] kauditd thread API fixes

[Jeff Garzik <jeff@garzik.org>]

Kill the "function should return a value" warning, and use the standard
mechanism for deciding when a thread should stop.

Given the security-sensitive nature of the audit function, _perhaps_ the
omission of kthread_should_stop() was intentional.  If so, it at least
deserves a comment.  But I think this is more correct.
