/* Check for --listen-address options that haven't been used because there's
no interface with a matching address. These may be valid: eg it's possible
to listen on 127.0.1.1 even if the loopback interface is 127.0.0.1
If the address isn't valid the bind() will fail and we'll die().
The resulting listeners have the ->iface field NULL, and this has to be
handled by the DNS and TFTP code. It disables --localise-queries processing
(no netmask) and some MTU login the tftp code. */
