ide scsi virtio-blk: Reject empty drives unless media is removable
Disks without media make no sense. For SCSI, a Linux guest kernel complains during boot. I didn't try other combinations. scsi-generic doesn't need the additional check, because it already requires bdrv_is_sg(), which fails without media.
