Fix Invalid node address specified in redis-cli --cluster create/add-node (redis#11151)

This bug was introduced in redis#10344 (7.0.3), and it breaks the
redis-cli --cluster create usage in redis#10436 (7.0 RC3).

At the same time, the cluster-port support introduced in redis#10344
cannot use the DNS lookup brought by redis#10436.
