[PATCH] wined3d: Fully initialise "settings" in wined3d_ffp_get_vs_settings().

[Henri Verbeet]

Commit b62f4139eda58e8e25cbc58864fcea2599a20e97 introduced implicit padding in
the wined3d_ffp_vs_settings structure. This causes redundant shader variants
to be generated. Although easy to avoid, there's also something to be said for
being more robust against padding.
