vhost-user-vsock-pci: force virtio version 1
Commit 9b3a35ec82 ("virtio: verify that legacy support is not
accidentally on") added a safety check that requires to set
'disable-legacy=on' on vhost-user-vsock-pci device:
$ ./qemu-system-x86_64 ... \
-chardev socket,id=char0,reconnect=0,path=/tmp/vhost4.socket \
-device vhost-user-vsock-pci,chardev=char0
qemu-system-x86_64: -device vhost-user-vsock-pci,chardev=char0:
device is modern-only, use disable-legacy=on
virtio-vsock was introduced after the release of VIRTIO 1.0
specifications, so it should be 'modern-only'.
This patch forces virtio version 1 and removes the 'transitional_name'
property, as done for vhost-vsock-pci, removing the need to specify
'disable-legacy=on' on vhost-user-vsock-pci device.
