[RFC PATCH 4/7] audit: wake up threads if queue switched from limited to unlimited

[Richard Guy Briggs]

If the audit_backlog_limit is changed from a limited value to an
unlimited value (zero) while the queue was overflowed, wake up the
audit_backlog_wait queue to allow those processes to continue.
