So far virtio-scsi-device can't expose host features to guest while using virtio-mmio because it doesn't set DEFINE_VIRTIO_SCSI_FEATURES on backend or transport. The host features belong to the backends while virtio-scsi-pci, virtio-scsi-s390 and virtio-scsi-ccw set the DEFINE_VIRTIO_SCSI_FEATURES on transports. But they already have the ability to forward property accesses to the backend child. So if we move the host features to backends, it doesn't break the backwards compatibility for them and make host features work while using virtio-mmio. Move DEFINE_VIRTIO_SCSI_FEATURES to the backend virtio-scsi. The transports just sync the host features from backends.
