virtio-scsi.h: Add virtio_scsi_cmd_req_pi + VIRTIO_SCSI_F_T10_PI bits

This patch adds a virtio_scsi_cmd_req_pi header as recommened by
Paolo that contains pi_bytesout + pi_bytesin elements used for
signaling when protection information buffers (in bytes) are
expected to preceed the data payload buffers.

Also add new VIRTIO_SCSI_F_T10_PI feature bit to be used to signal
host support.
