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 
etc...).

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..
