function DxEngGetHdevData 
pdev->hSpooler is a pointer to PDEVICE_OBJECT but in books it marks as handle.
hSpooler is where u loading in printer drv or second time same graphic drv.
ReactOS does not support printer or loading second time same graphic drv 
so we point it to PDev->pGraphicsDevice->DeviceObject
