If you called pD3DKKMTOpenAdapterFromGdiDisplayName( NULL ) here you
wouldn't leak the adaptor handle.  This would also get the invalid
parameter test out of the way.

There doesn't seem to be a need to test for D3DKMTCloseAdaper, we can
assume that's going to be present if we get this far.

Similar things apply to other patches in the series.

Huw.
