SCSI fixes on 20190720

Browse Source 
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.
