hsfetch hs_desc FAILED with REASON missing
Controller...
hsfetch tries to fetch from up to 6 hsdirs. If for any reason, such as network or hsdir appearing down anomalies, none of the 6 respond (or possibly even do not respond in a recognized manner), hs_desc fails to print FAILURE, which means REASON is missing, and anything using the controller is left ambiguous.
hs_desc event should print result of hsfetch in all cases.
