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.
