[PATCH 4/5] vhost-scsi: add VIRTIO_F_VERSION_1 and VIRTIO_F_RING_PACKED

[Stefan Hajnoczi]

Let vhost-scsi and vhost-user-scsi device backends determine whether
VIRTIO 1.0 and packed virtqueues are supported. It doesn't make sense to
handle these feature bits in QEMU since the device backend needs to
support them if we want to use them.
