From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
Use the 'completed?' tracepoint field to detect more robustly when a
request has been preempted and remove it from the engine database if so.
Otherwise the script can hit a scenario where the same global seqno will
be mentioned multiple times (on an engine seqno) which aborts processing.
