You can't AFAIK.

Bind is stopping listening because the interface has gone down. If you 
don't want it to stop listening, don't let the interface down.

As you've discovered, the other option is to call "rndc reconfig" when 
the interface comes back up; bind will re-discover the IPs. You could do 
this automatically if your distribution supports interface "scripts" 
e.g. /sbin/ifup-local
