   If we don't receive a reply packet the res_send subquery will already have
   set subq_h_errno and ar_count. Remove the ar_datalen == -1 check, so we
   set ar_h_errno and don't have to (wrongly) guess that
   ar_h_errno = HOST_NOT_FOUND.

   This makes sure that if no nameserver responds the h_errno value is set to
   TRY_AGAIN instead of HOST_NOT_FOUND.

   OK eric@, deraadt@
