 On second thought, is this really necessary?  Since a router won't
 have ri->ipv6_preferred set unless we've seen an IPv6 address in its
 descriptor fetching by preferred address won't fail.

 What worries me more is the way
 get_configured_bridge_by_addr_port_digest() might return a bridge with
 another address than the one we ask for.  This might happen when we
 don't pass it a digest.  How bad would that be?
