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: b2807f07f4 ("mm: memcontrol: add "sock" to cgroup2 memory.stat")
