SCSI fixes on 20160211

Browse source 
A set of seven fixes.  Two regressions in the new hisi_sas arm driver, a
 blacklist entry for the marvell console which was causing a reset cascade
 without it, a race fix in the WRITE_SAME/DISCARD routines, a retry fix for the
 rdac driver, without which, it would prematurely return EIO and a couple of
 fixes for the hyper-v storvsc driver.
