netfilter: ctnetlink: don't use conntrack/expect object addresses as id
[ Upstream commit 3c79107631db1f7fd32cf3f7368e4672004a3010 ]
else, we leak the addresses to userspace via ctnetlink events
and dumps.
Compute an ID on demand based on the immutable parts of nf_conn struct.
Another advantage compared to using an address is that there is no
immediate re-use of the same ID in case the conntrack entry is freed and
reallocated again immediately.
