Ondřej Surý 1af37e24b2 Open the stale-refresh-time window on any resolver failure ... The TCP-fallback fix in the previous commits means a query that would previously have timed out on UDP now actually escalates to TCP, and a TCP-side failure surfaces a non-ISC_R_TIMEDOUT result code to query_usestale(). The trigger for DNS_DBFIND_STALESTART was previously narrowed to ISC_R_TIMEDOUT, so the stale-refresh-time window stopped opening for those clients. Broaden the condition to any failure that has already cleared the upstream DUPLICATE/DROP filtering in query_usestale() — the spirit of the window is "the resolver tried and could not get a fresh answer", not "the resolver timed out specifically".
