    st/mesa: set sampler_view::last_level correctly
    
    It was set to pipe_resource::last_level and _MaxLevel was embedded in max_lod,
    that's why it worked for ordinary texturing. However, min_lod doesn't have
    any effect on texelFetch and textureQueryLevels, so we must still set
    last_level correctly.
