generally skip throwing away opened sockets on EADDRNOTAVAIL

I'm suppose the same could (in the future) happen for IPv4 (or other
protocols), it might be better not to limit it to IPv6.

Darren, do you have any concerns about this sort of limiting? AFAIU,
the only way CVE-2008-1483 could creep back in is that someone enables
disabled protocol and starts listening on the same port that is already
used (with the address family that was available at the moment the
connection was established).
