Matthijs Mekking b90bad93cb Fix serve-stale bug when cache has no data ... We recently fixed a bug where in some cases (when following an expired CNAME for example), named could return SERVFAIL if the target record is still valid (see isc-projects/bind9#3678, and isc-projects/bind9!7096). We fixed this by considering non-stale RRsets as well during the stale lookup. However, this triggered a new bug because despite the answer from cache not being stale, the lookup may be triggered by serve-stale. If the answer from database is not stale, the fix in isc-projects/bind9!7096 erroneously skips the serve-stale logic. Add 'answer_found' checks to the serve-stale logic to fix this issue.
