No, he completed a shit ton of other quests before he went and gave it away. Plus, he raided Uthar's personal room both before and after the slaughter of the Sith Academy. Like AP said, the chances he didn't retrieve it on any of those encounters is fallacious because Traya states the holocron is gone (not in the Sith Academy or anywhere else, meaning Revan would have taken it).
