wined3d: Compare num_params against 1 in shader_glsl_map2gl().

[Henri Verbeet]

num_params includes the destination parameter, while we're only interested in
source parameters. This doesn't cause problems for any of the instrctions
currently handled by shader_glsl_map2gl() though, since they all happen to
have at least 1 source parameter.
