SCSI fixes on 20170119 

This is a set of 12 fixes including the mpt3sas one that was causing
 hangs on ATA passthrough.  The others are a couple of zoned block
 device fixes, a SAS device detection bug which lead to SATA drives not
 being matched to bays, two qla2xxx MSI fixes, a qla2xxx req for rsp
 confusion caused by cut and paste, and a few other minor fixes.
