The interface uses bytes instead of iovecs as the unit, and
vhost-scsi can add the (temporary...) requirement that do_pi_nbytes
and di_pi_nbytes comprise an integer number of iovecs.

That would be a reasonable intermediate step, but

So this looks like a somewhat problematic interface to me

This patch adds a virtio_scsi_cmd_req_pi header as recommened by
Paolo that contains do_pi_niov + di_pi_niov elements used for
signaling when protection information buffers are expected to
preceed the data buffers.
Also add new VIRTIO_SCSI_F_T10_PI
