wined3d: Set default sampler minification filter to GL_NEAREST.

This seems to be required for reading stencil values. The GL spec says "When sampling the stencil index only NEAREST filtering is supported.". The GL spec is inconsistent about this, but Mesa refuses to sample stencil index values with the GL_NEAREST_MIPMAP_NEAREST filter.
