SCSI fixes on 20180306

Browse source 
This patch is mostly fixes for driver specific issues (nine of them)
 and the storvsc performance improvement with interrupt handling which
 was dropped from the previous fixes pull request.  We also have two
 regressions: one is a double call_rcu() in ATA error handling and the
 other is a missed conversion to BLK_STS_OK in
 __scsi_error_from_host_byte().
