I'm not sure if I understand you correctly.  How does register_target create a
circular list?

initially, iptables_targets == NULL.
then you register the first target (t), and you set t->next = iptables_targets
(== NULL), and then point iptables_targets to t. 
Result: iptables_targets == t; t->next == NULL.  
if you register a second target (t2).
Result: iptables_targets == t2, t2->next == t, t->next == NULL.

Maybe you can be a bit more verbose
