devlink_nl_rate_parent_fill() emits DEVLINK_ATTR_PARENT_DEV via devlink_nl_put_nested_handle(), which adds DEVLINK_ATTR_NETNS_ID whenever the parent rate node lives on a devlink instance in another netns. Now that we defined dl-nested-devlink subset, which unlike dl-parent-dev includes netns-id, let's switch to it. The rate APIs input genuinely does not accept the netns-id, so we need to subset them to stick with dl-parent-dev.
