    Ensure ns_query_cancel() handles all recursions · eb8a2737

    Previously, multiple code paths reused client->query.fetch, so it was
    enough for ns_query_cancel() to issue a single call to
    dns_resolver_cancelfetch() with that fetch as an argument.  Now, since
    each slot in the 'recursions' array can hold a reference to a separate
    resolver fetch, ns_query_cancel() needs to handle all of them, so that
    all recursion callbacks get a chance to clean up the associated
    resources when a query is canceled.
