    This patch updates virtscsi_probe() to setup necessary Scsi_Host
    level protection resources. (currently hardcoded to 1)
    
    It changes virtscsi_add_cmd() to attach outgoing / incoming
    protection SGLs preceeding the data payload, and is using the
    new virtio_scsi_cmd_req_pi->pi_bytes[out,in] field to signal
    to signal to vhost/scsi bytes to expect for protection data.
    
    (Add missing #include <linux/blkdev.h> for blk_integrity - sfr + nab)
