fs: handle failed audit_log_start properly
commit d1c7d97ad58836affde6e39980b96527510b572e upstream.
audit_log_start() may return NULL, this is unchecked by the caller in
audit_log_link_denied() and could cause a NULL ptr deref.
Introduced by commit a51d9eaa ("fs: add link restriction audit reporting").
