Fix to track-kameipv6 branch for socket.c

[Villalovos, John L]

I ran into a problem where systems without DNS entries could not connect to
the rsync server with the IPV6 patch applied.

Here is a fix to the problem.

Basically they were checking the list of IP addresses returned by getaddr
even if getaddr failed.  I just changed it so they only check the list of IP
addresses if getaddr succeeds.

Any comments on this please email me directly because I do not belong to
this mailing list.  The reason I fixed this is because the rsync RPM that
comes with Red Hat 7.2 contained the IPV6 patch in it.

Later,
John
