Removed unused code

	image = PyObject_CallFunction(fill, "ii", width, height);
	if (image == Py_None) {
	PyMem_Del(glyph_info);
	return Py_BuildValue("N(ii)", image, 0, 0);

The scenario where the Python fill() function might return None began in #7247. However, when it was removed in #7645, the C code to handle it stayed. This PR now removes that code.
