The current implementation does not like RADIUS_CLIENT_MAX_ENTRIES = 0
value at all, i.e., it depends on being able store at least one entry
even if it would not actually end up being used for a retry. Just
changing the RADIUS_CLIENT_MAX_RETRIES value and leaving everything else
unmodified should be enough. It may not currently prevent all retries,
but it did seem to limit retries when the max entries limit was not
