ipv6: snmp: do not track per idev ICMP6_MIB_RATELIMITHOST
Blamed commit added a critical false sharing on a single
atomic_long_t under DOS, like receiving UDP packets
to closed ports.
Per netns ICMP6_MIB_RATELIMITHOST tracking uses per-cpu
storage and is enough, we do not need per-device and slow tracking.
Fixes: d0941130c9351 ("icmp: Add counters for rate limits")
