sysfs, kernfs: make sysfs_super_info->ns const
Add const qualifier to sysfs_super_info->ns so that it's consistent with other namespace tag usages in sysfs. Because kobject doesn't use const qualifier for namespace tags, this ends up requiring an explicit cast to drop const qualifier in free_sysfs_super_info().
