The way the link control helper works is by setting the error rate of a channel to 1.0, so that no packets are able to make it to the other end of the link. However, NFD is not aware of this change, since the best route strategy determines which should be the next hop based on its cost. I would suggest that you use another forwarding strategy, for example the ASF strategy (section 5.2.6 in the NFD developer’s guide):
