Mark a primary as unreachable on timed out in xfin

Browse source 
When a primary server is not responding, mark it as temporarialy
unreachable.  This will prevent too many zones queuing up on a
unreachable server and allow the refresh process to move onto
the next primary sooner once it has been so marked.
