Make ReplayStage panic before dumping repeated-repair-attempt slots (#31333) 

When ReplayStage repeatedly fails to compute the correct for a block
after purging and repairing, it panics on the assumption that something
is very wrong and will require human intervention.

If this is the case, there is typically something to be debugged, and
having the slot available locally is valuable. This change does the
retry check that will panic before purging the failure slot.
