[NTOSKRNL] Add a quick path for FileFsDeviceInformation in NtQueryVolumeInformationFile
This allows querying volume information without issuing an IRP to the owner device.
The kernel is supposed to already have all the required information to return
to the caller.

Side effect: this allows querying volume information for devices not implementing
IRP_MJ_QUERY_VOLUME_INFORMATION such as null.sys
This fixes opening null device in Python.

Fix based on debugging by Maxim Smirnov in PR #1442
