[greatlrd] 33221: Bugfix ntoskrnl : IoBuildAsynchronousFsdRequest the param DeviceObject, can be NULL when it comes from dxg.sys for dxg will set it only for AGP graphic card or newer. Cleanup : intEnableReactXDriver it contain less code now. for most of the work are done by dxg.sys. now ms dxg.sys fill the edd_directdraw_gloabl struct by it self.

Log:
Bugfix ntoskrnl : IoBuildAsynchronousFsdRequest the param DeviceObject, can be NULL when
it comes from dxg.sys for dxg will set it only for AGP graphic card or newer.
Cleanup : intEnableReactXDriver it contain less code now. for most of the work are done by
dxg.sys.
now ms dxg.sys fill the edd_directdraw_gloabl struct by it self.
