[fireball] 26222: - Fix a few obvious bugs (incorrect DeviceExtension pointer arithmetic, non-initialized field usage). - Packets are sequentially numbered. Now all devices are perfectly enumerated (SpBuildDeviceMap() may still need work, but later), and problem occurs later when servicing IOCTLs.

Log:
- Fix a few obvious bugs (incorrect DeviceExtension pointer arithmetic, non-initialized field usage).
- Packets are sequentially numbered.

Now all devices are perfectly enumerated (SpBuildDeviceMap() may still need work, but later), and problem occurs later when servicing IOCTLs.
