Log:
[SCSIPORT]: Fixes:
- In SpiScanAdapter(), after an SCSI INQUIRY command has succeeded and we are setting up a LUN extension structure,
  cache in its InquiryData member the inquiry data retrieved from the INQUIRY command (alternatively we might just cache
  a pointer to a valid "LunInfo" since the latter are also cached elsewhere).
- This allows SpiBuildDeviceMap(), which is called just after SpiScanAdapter(), to correctly report in the registry SCSI tree
  the correct Identifier and DeviceType values for the enumerated logical units.
- Use ExFreePoolWithTag in SpiScanAdapter().
