mesa: Handle GL_COLOR_INDEX in _mesa_format_from_format_and_type().
Just return MESA_FORMAT_NONE to avoid triggering unreachable; there's
really no sensible thing to return for this case anyway.
This prevents regressions in the next commit, which makes st/mesa
start using this function to find a reasonable format from GL format
and type enums.
