ping: implement proper locking
We got a report of yet another bug in ping
http://www.openwall.com/lists/oss-security/2017/03/24/6
->disconnect() is not called with socket lock held.
Fix this by acquiring ping rwlock earlier.
Thanks to Daniel, Alexander and Andrey for letting us know this problem.
Fixes: c319b4d76b9e ("net: ipv4: add IPPROTO_ICMP socket kind")
