   When a timeout happens we don't know what's the state of the remote end,
   so there is no point in doing anything else since it will most probably
   fail anyway.
   
   The change also demotes the log message printed when falling back to
   SASL, since a warning is too noisy for when the fallback is really
   needed (e.g. old shuffle service, or shuffle service with new auth
   disabled).
