netfilter: nf_conncount: speculative garbage collection on empty lists
Instead of removing a empty list node that might be reintroduced soon thereafter, tentatively place the empty list node on the list passed to tree_nodes_free(), then re-check if the list is empty again before erasing it from the tree.
