SCSI misc on 20170303 

This is the set of stuff that didn't quite make the initial pull and a
 set of fixes for stuff which did.  The new stuff is basically lpfc
 (nvme), qedi and aacraid.  The fixes cover a lot of previously
 submitted stuff, the most important of which probably covers some of
 the failing irq vectors allocation and other fallout from having the
 SCSI command allocated as part of the block allocation functions.
