I think this patch makes sense, but could you please add a test case
as well? Ideally we'd also have similar tests for other resources
(i.e., textures, volumes, vertex buffers, index buffers) and D3D
versions (ddraw, d3d8), but that's not a strict requirement.

Minor style issue, this should be:

if (SUCCEEDED(hr))
    {
        ...
    }
