[NTOS:IO] Reformat iorsrce.c, no functional code changes.

- Fix whitespace; add SAL annotations, doxygen documentation...

- Deduplicate the array of description strings corresponding to
  IO_QUERY_DEVICE_DATA_FORMAT.

- Unhardcode the "[3]" into 'IoQueryDeviceMaxData': the maximum number
  of device data queried.
