Since a9e97e0c we don't require driver->config, or
virQEMUDriverGetConfig() to be called with locked QEMU driver. In fact,
calling it with the driver locked would cause deadlock. Hence, the

Actually, it is 'immutable pointer, immutable+lockless data', since
we don't require any locks to be held in order to access fields in
the config object.
