Title: aqm/codel: remove timestamp update from pull

This can be accomplished by adding a SetTimestampDelta, so no need to do it
here. Furthermore, it does not check to see whether the Timestamp was empty
or not, so it is setting a weird Timestamp on packets that might have just
been passed-through.
