d3d9: Some Windows drivers do not like reversed fog.

The fog test used start = 0.9 and end = 0.1. This is perfectly ok in theory, but some Windows drivers do not like it. Since this test tests how fog is calculated with Vertex and Pixel shaders put the fog range in the normal order(start = 0.1, end = 0.9), this fixes a number of fog failures on ATI cards on Windows.
