Clear the address when we can't choose a reachable address 

When the fascist_firewall_choose_address_ functions don't find a
reachable address, set the returned address to the null address and port.

This is a precautionary measure, because some callers do not check the
return value.

Fixes bug 24736; bugfix on 0.2.8.2-alpha.
