Brad Fitzpatrick 1b6bc37f28 net/dnscache: fix case where Resolver could return zero IP with single IPv6 address
The controlhttp dialer with a ControlDialPlan IPv6 entry was hitting a
case where the dnscache Resolver was returning an netip.Addr zero
value, where it should've been returning the IPv6 address.

We then tried to dial "invalid IP:80", which would immediately fail,
at least locally.

Mostly this was causing spammy logs when debugging other stuff.
