Subject: mm: memcontrol: drop superfluous entry in the per-memcg stats array
MEM_CGROUP_STAT_NSTATS is just a delimiter for cgroup1 statistics, not an
actual array entry. Reuse it for the first cgroup2 stat entry, like in
the event array.
Fixes: b2807f07f4f8 ("mm: memcontrol: add "sock" to cgroup2 memory.stat")
