[PATCH 03/10] xeniface: close thread handle after ObReferenceObjectByHandle in session create

[david ambu <david.preetham@xxxxxxxxxx>]

PsCreateSystemThread creates a kernel handle that was never closed.
Add ZwClose(hthread) after taking the object reference via
ObReferenceObjectByHandle, releasing the handle table entry
immediately as it is no longer needed.
