libcnary: Fix possible NULL pointer dereference in node_iterator_create()
When NULL is passed to node_iterator_create() the code tries to access the begin element of the node list and causes a NULL pointer dereference. The value of list is checked a few lines down and iterator->value is then properly assigned in node_iterator_bind().
