DPD: log analyzers that have confirmed

Browse source 
This switches the DPD logic to always log analyzers that raised a
protocol confirmation.

The logic is that, once a protocol has been confirmed - and thus there
probably is log output - it does not make sense to later remove it from
the log. It does make sense to somehow flag it as failed - but that
seems like a secondary step.
