overlay/d3d9: pass through IDirect3DDevice9 AddRef/Release methods to originals on Windows 8.

We were getting unbalanced AddRef/Releases on Direct3D9 apps running on Windows 8 that ran
fine on Windows 7.  Windows 8 seems to be doing somthing funky with the internal ref count
of IDirect3DDevice9.

For now, piggyback on the orignal ref count methods to be able to determine when to release
ourselves. And cross our fingers that we won't be getting useless ref counts from some other
overlay.

This is a band-aid solution until we find something better.
