Remove unnecessary callbacks that simply return -EOPNOTSUPP for following map operations: - map_peek_elem - map_push_elem - map_pop_elem - map_delete_elem - map_get_next_key These operations are not supported for certain map types and can be handled by generic map code instead of having redundant single-line callbacks.
