eigrp: Don't dereference NULL timer in a Neighbour

Current, a eigrp_neighbor only has a t_holddown timer when in state
EIGRP_NEIGHBOR_PENDING and EIGRP_NEIGHBOR_UP. In state
EIGRP_NEIGHBOR_DOWN it could be a NULL pointer. Don't dereference the
timer when dumping the neighbour table without first checking it
exists. If it does not exist, display - instead of the remaining time.
