I don't think mummies show up a second time after being defeated, and there's no reason Dong Huo should be an exception. So I'd say the fact that your sim could get the same quest is either a typical Sims 3 bug (the first part of the chain shouldn't be repeatable) or a random glitch (the data that your sim finished the quest was erased). I wouldn't worry about it though, and the only thing you really could have done was cancel the quest.
