af_key: Add lock to key dump
commit 89e357d83c06b6fac581c3ca7f0ee3ae7e67109e 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: 83321d6b9872 ("[AF_KEY]: Dump SA/SP entries non-atomically")
