Kuniyuki Iwashima ab5fb73ffa ping: Fix potentail NULL deref for /proc/net/icmp. 
After commit dbca1596bb ("ping: convert to RCU lookups, get rid
of rwlock"), we use RCU for ping sockets, but we should use spinlock
for /proc/net/icmp to avoid a potential NULL deref mentioned in
the previous patch.

Let's go back to using spinlock there.

Note we can convert ping sockets to use hlist instead of hlist_nulls
because we do not use SLAB_TYPESAFE_BY_RCU for ping sockets.

Fixes: dbca1596bb ("ping: convert to RCU lookups, get rid of rwlock")
