[Qemu-devel] [PULL v2 27/49] virtio: split virtio scsi bits from virtio-pci

["Michael S. Tsirkin" <mst@redhat.com>]

From: Juan Quintela <quintela@redhat.com>

Notice that we can't still run tests with it disabled.  Both cdrom-test and
drive_del-test use virtio-scsi without checking if it is enabled.
