This enables VhostVDPAState to track the logging of the memory. It cannot be merged with s->always_svq because always_svq is immutable from the moment the device is parsed, and log_enabled must be enabled or disabled depending on the log state. Apart from that, they will affect the same to vhost vdpa device, enabling the shadow virtqueue unconditionally.
