[PATCH] dxgi/tests: Check that the last adapter is always WARP.

[Rémi Bernon]

Some games specifically ignore the last adapter from the adapter list,
as it's always WARP on Windows. This makes them fail to detect GPUs
correctly on Wine, as they drop one of the reported adapters.

I also have a patch to add a WARP adapter to the list in wined3d, but I
think there's some multi-adapter work under way that will conflict, so
I'll wait before sending it.
