Aleksa Sarai a288d14bb7 cgroup: pids: use atomic64_t for pids->limit ...

commit a713af394c upstream.

Because pids->limit can be changed concurrently (but we don't want to
take a lock because it would be needlessly expensive), use atomic64_ts
instead.

Fixes: commit 49b786ea14 ("cgroup: implement the PIDs subsystem")
