[PATCH] kauditd_thread warning fix

Squash this warning:

  kernel/audit.c: In function 'kauditd_thread':
  kernel/audit.c:367: warning: no return statement in function returning non-void

We might as test kthread_should_stop(), although it's not very pointful at
present.

The code which starts this thread looks racy - the kernel could start multiple
threads.
