commit 4542d623c7134bc1738f8a68ccb6dd546f1c264f upstream. Commands with protection information included were not truncating the protection iov_iter to the number of protection bytes in the command. This resulted in vhost_scsi mis-calculating the size of the protection SGL in vhost_scsi_calc_sgls(), and including both the protection and data SG entries in the protection SGL.
