[PATCH v4 3/5] ntoskrnl.exe: Implement volume information queries for device files.

This patch implements volume information queries for device files,
which allows NtQueryVolumeInformationFile to issue
IRP_MJ_QUERY_VOLUME_INFORMATION to return volume information from a
driver.  The patch also now includes a simple test that issues
FileFsVolumeInformation (for systems that support unsigned drivers).

v4: Split out content from server/device.c and
dlls/ntoskrnl.exe/ntoskrnl.c, fixed copy-paste error identified by
Zeb, and added tests

Best,
Erich
