SCSI misc on 20200613 

This is the set of changes collected since just before the merge
 window opened.  It's mostly minor fixes in drivers.  The one
 non-driver set is the three optical disk (sr) changes where two are
 error path fixes and one is a helper conversion.  The big driver
 change is the hpsa compat_alloc_userspace rework by Al so he can kill
 the remaining user.  This has been tested and acked by the maintainer.
