Merge branch 'stable-4.11' of git://git.infradead.org/users/pcmoore/audit

Pull audit fix from Paul Moore:
 "One more small audit fix, this should be the last for v4.11.

  Seth Forshee noticed a problem where the audit retry queue wasn't
  being flushed properly when audit was enabled and the audit daemon
  wasn't running; this patches fixes the problem (see the commit
  description for more details on the change).

  Both Seth and I have tested this and everything looks good"

* 'stable-4.11' of git://git.infradead.org/users/pcmoore/audit:
  audit: make sure we don't let the retry queue grow without bounds
