[PATCH 2/5] wined3d: Check all the ffp_material fields.

[Matteo Bruni]

The application can override each material parameter with one of the two
FFP vertex color attributes. The 'ambient' struct field in the GLSL shader
can thus happen to be unused and the GL driver may optimize it away.

Fixes bug 38532.
