- Reduced the necessary size of inquiry data to 4 byte.

Browse source 
- Incremented the active irp counters in SpiAddActiveIrp,
  because the valid value is necessary in this function while starting new irp's.
- Do not set the command queueing enable flag in SpiAddActiveIrp,
  because this is the job of a driver above scsiport.
