[libvirt] [PATCH 2/2] qemu: add virtio-scsi controller model



Adding a new model for virtio-scsi roughly follows the same scheme
as the previous patch.

Signed-off-by: Paolo Bonzini <pbonzini redhat com>
---
	This is the bare minimum necessary to use virtio-scsi.
	I'll gladly leave everything else, including support for
	full SCSI addresses (target/LUN) to Osier.
