The `BKE_material_pop_id()` and `BKE_material_clear_id()` functions had a parameter `update_data` that, when `false`, would cause the mesh polys to keep their material index, even when the indexed material slots were removed. This behaviour was never used in the C code and not supported by the drawing code, making polygons disappear and causing crashes. The Python binding in RNA, however, defaulted to `update_data=False`. This commit removes the `update_data` parameter altogether, and makes the functions always fix up the material indices. Reviewed by: mont29, brecht
