Review Comment:
Retry for this case is doesn't look at lastProducerEpoch, so either way is
fine there. I think the big question is if we get a benefit from initProducerId
by not updating the epoch here. The valid epoch check can be changed if we
decide not to update between prepare and complete.
Let me know if I'm missing something
