Matthijs Mekking 8bcd7fe69e Use stale on error also when unable to recurse ...

The 'query_usestale()' function was only called when in
'query_gotanswer()' and an unexpected error occurred. This may have
been "quota reached", and thus we were in some cases returning
stale data on fetch-limits (and if serve-stale enabled of course).

But we can also hit fetch-limits when recursing because we are
following a referral (in 'query_notfound()' and
'query_delegation_recurse()'). Here we should also check for using
stale data in case an error occurred.

Specifically don't check for using stale data when refetching a
zero TTL RRset from cache.

Move the setting of DNS_DBFIND_STALESTART into the 'query_usestale()'
function to avoid code duplication.
