Add <hostdev> protocol=vhost model handling for virtio transitional
devices. Ex:
<hostdev mode='subsystem' type='scsi_host' model='virtio-transitional'>
<source protocol='vhost' wwpn=X/>
</hostdev>
* "virtio-transitional" maps to qemu "vhost-scsi-pci-transitional"
* "virtio-non-transitional" maps to qemu "vhost-scsi-pci-non-transitional"
