ping: convert to RCU lookups, get rid of rwlock
Using rwlock in networking code is extremely risky.
writers can starve if enough readers are constantly
grabing the rwlock.
I thought rwlock were at fault and sent this patch:
https://lkml.org/lkml/2022/6/17/272
But Peter and Linus essentially told me rwlock had to be unfair.
We need to get rid of rwlock in networking code.
Fixes: c319b4d76b9e ("net: ipv4: add IPPROTO_ICMP socket kind")
