D7325: KCupsConnection: Exit authentication loop after too many retries.

REVISION SUMMARY
  This fixes endless loops for example in the situation
  if the server uses IP whitelisting and denies our host
  with 403 on each administrative request.
  In that case, the passwort_attempt counter is never increased,
  which up to now was the only exit condition.
  The total_retries counter catches any case in which the
  cups API will not call the password callback.
