Pull SCSI fixes from James Bottomley:
 "This is the final round of mostly small fixes in our initial submit.

  It's mostly minor fixes and driver updates. The only change of note is
  adding a virt_boundary_mask to the SCSI host and host template to
  parametrise this for NVMe devices instead of having them do a call in
  slave_alloc. It's a fairly straightforward conversion except in the
  two NVMe handling drivers that didn't set it who now have a virtual
  infinity parameter added"
