    [SDK][PSDK] Add a version check for DiskGeometryGetPartition and 
DiskGeometryGetDetect and add a missing member to PARTITION_INFORMATION_EX 
structure (#2541)
    
    DiskGeometryGetPartition() and DiskGeometryGetDetect() are guarded in 
NTDDI_VERSION for version checking as they differ between Windows XP and Server 
2003. In conjunction to that, the PARTITION_INFORMATION_EX structure has 
"IsServicePartition" as member which is missing in the current NT IOCTL Disk 
interface header.
