if machined exits while a machine is still running, we'll issue the UnrefUnit() call on the unit. This quite likely will fail if during shutdown the bus connection is already down. But that's no reason to warn at all, since the ref count will implicitly be dropped if our side disappears from the bus. Hence, downgrade to LOG_DEBUG in case of connection problems.
