In the event MK_INET6 != no in userspace, but is disabled in the
kernel, or if there aren't any IPv6 addresses configured in userspace
(for lo0 and all physical interfaces), rpcbind would terminate
immediately instead of silently failing on

Skip over the IPv6 block to its respective cleanup with freeifaddrs if
creating the socket failed instead of terminating rpcbind immediately
