  Log:
  Add PIM_SEQSCAN for HBA misc flags and code that understands
  what to do with it.
  
  This forces us to scan targets sequentially, not in parallel.
  The reason we might want to do this is that SPI negotiation
  might not work right at the SIM level if we try to do it
  in parallel.
  
  If PIM_SEQSCAN is not set (default), the original behaviour for
  probing is unchanged.
  
  LUN probing is still done in parallel for each target in either
  case.
