sched: remove redundant NULL cgroup check in task_group_path()
A task_group won't be online (thus no one can see it) until cpu_cgroup_css_online(), and at that time tg->css.cgroup has been initialized, so this NULL check is redundant. Signed-off-by: Li Zefan <lizefan@huawei.com> Signed-off-by: Tejun Heo <tj@kernel.org>
