[SCSIPORT]: Fixes + documentation:

- In SpiSendInquiry():
  * use ExFreePoolWithTag;
  * if IoBuildDeviceIoControlRequest() fails, exit correctly the loop so that the allocated buffers are cleaned up;
- In SpiBuildDeviceMap():
  * support new peripheral type names, as documented in the links in the comments;
  * fix the "CommunicationsPeripheral" name (communication'S') as documented, and as done in windows' scsiport driver.
