SCSI fixes on 20180222 

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.
