smack: call WARN_ONCE() instead of calling audit_log_start()
Remove the call to audit_log() (which call audit_log_start()) and deal with the errors in the caller, logging only once if the condition is met. Calling audit_log_start() in this location makes buffer allocation and locking more complicated in the calling tree (audit_filter_user()).
