cgroup: make interface file "cgroup.sane_behavior" legacy-only
"cgroup.sane_behavior" is added to help distinguishing whether sane_behavior is in effect or not. We now have the default hierarchy where the flag is always in effect and are planning to remove supporting sane behavior on the legacy hierarchies making this file on the default hierarchy rather pointless. Let's make it legacy only and thus always zero. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Li Zefan <lizefan@huawei.com>
