SCSI misc on 20160315 

This pull includes driver updates from the usual suspects (stex, hpsa,
 ncr5380, scsi_dh, qla2xxx, be2iscsi, hisi_sas, cxlflash, aacraid,
 mp3sas, megaraid_sas, ibmvscsi, ufs) plus an assortment of
 miscellaneous fixes.  The major user visible change of this pull is
 that we've moved from monotonically increasing host number to an ida
 allocated one (meaning the numbers get re-used) because someone
 managed to wrap the count in an iscsi system.  We don't believe there
 will be any adverse consequences of this.
