These two tests for slightly different things
The first checks that there is a timeout.
The second checks that the conntrack entry is active (in the hash table
The two is at most if not all times equal as all active conntrack entries
have a timeout of some sort, but maybe it is possible for the timeout to
be established before the conntrack becomes confirmed or something..
