Track preauth failures instead of tries

In preauth2.c, instead of noting whenever we try a real preauth mech,
note when a mechanism fails on our side.  Tracking only failures
eliminates the need to reset the list for multi-step preauth exchanges
or for processing padata in the AS-REP, but we will need the function
later for continuing after optimistic preauth failures.
