"addr" is the result of net.JoinHostPort which supports IPv6 address.
Rather than ranging "tp.Endpoints" again, it's better to reuse
"addr" in the first loop to collect "eps".
See #7942 and #7943 for context.

formatAddr is just like net.JoinHostPort, I think we can use net.JoinHostPort
directly, it's simpler and clearer.
