SCSI fixes on 20180222

Browse Source 
These are mostly fixes for problems with merge window code.  In
 addition we have one doc update (alua) and two dead code removals
 (aiclib and octogon) a spurious assignment removal (csiostor) and a
 performance improvement for storvsc involving better interrupt
 spreading and increasing the command per lun handling.
