mm: memcontrol: use CSS_TASK_ITER_PROCS at mem_cgroup_scan_tasks()
Since commit c03cd7738a83 ("cgroup: Include dying leaders with live
threads in PROCS iterations") corrected how CSS_TASK_ITER_PROCS works,
mem_cgroup_scan_tasks() can use CSS_TASK_ITER_PROCS in order to check
only one thread from each thread group.
