Konstantin Khlebnikov 5047adbd85 audit: fix endless wait in audit_log_start() ...

commit 8ac1c8d5de upstream.

After commit 829199197a ("kernel/audit.c: avoid negative sleep
durations") audit emitters will block forever if userspace daemon cannot
handle backlog.

After the timeout the waiting loop turns into busy loop and runs until
daemon dies or returns back to work.  This is a minimal patch for that
bug.
