Yuejie Shi 0f94b36de3 af_key: Add lock to key dump 
commit 89e357d83c upstream.

A dump may come in the middle of another dump, modifying its dump
structure members. This race condition will result in NULL pointer
dereference in kernel. So add a lock to prevent that race.

Fixes: 83321d6b98 ("[AF_KEY]: Dump SA/SP entries non-atomically")
