xend: xenapi: Suspended domain causes fault if vif.get_all_records() is called

A single suspended domain on the system causes a fault when
vif.get_all_records() is called since this returns an ErrorDescription
and no 'Value' in the 'v' dictionary. This patch now returns a 'None'
as Value which might not be optimal but better than faulting.
