virtio-blk: remove SCSI passthrough functionality

Browse source 
The legacy SCSI passthrough functionality has never been enabled for
VIRTIO 1.0 and was deprecated more than four years ago.

Get rid of it---almost, because QEMU is advertising it unconditionally
for legacy virtio-blk devices.  Just parse the header and return a
nonzero status.
