audit: drop audit_cmd_lock in AUDIT_USER family of cases
We do not need to hold the audit_cmd_mutex for this family of cases. The
possible exception to this is the call to audit_filter_user(), so drop the lock
immediately after. To help in fixing the race we are trying to avoid, make
sure that nothing called by audit_filter_user() calls audit_log_start(). In
particular, watch out for *_audit_rule_match().
This fix will take care of systemd and anything USING audit. It still means
that we could race with something configuring audit and auditd shutting down.
