router: Stop advertising incorrect auto IPv6 ORPorts
When IPv6 ORPorts are set to "auto", tor relays and bridges would
advertise an incorrect port in their descriptor.
This may be a low-severity memory safety issue, because the published
port number may be derived from uninitialised or out-of-bounds memory
reads.
Fixes bug 32588; bugfix on 0.2.3.9-alpha.
