Subject: audit: reset audit backlog wait time after error recovery

commit e789e561a50de0aaa8c695662d97aaa5eac9d55f upstream.

When the audit queue overflows and times out (audit_backlog_wait_time), the
audit queue overflow timeout is set to zero.  Once the audit queue overflow
timeout condition recovers, the timeout should be reset to the original value.
