page_counter: track failcnt only for legacy cgroups
Currently page_counter tracks failcnt for counters used by v1 and v2
controllers. However failcnt is only exported for v1 deployment and thus
there is no need to maintain it in v2. The oom report does expose failcnt
for memory and swap in v2 but v2 already maintains MEMCG_MAX and
MEMCG_SWAP_MAX event counters which can be used.
