wined3d: Disable the depth stencil if it is smaller than the primary color buffer.

This way we get correct behavior if the application has depth and stencil related tests disabled. If we attach the depth stencil GL limits the framebuffer size to the smallest surface, making some parts of the framebuffer inaccessible.
