Hmmm, yeah, I think you're right.  It probably doesn't make a big
difference in the real world --- anyone who's dependent on the
performance of 2PC rollbaxks is Doing It Wrong.  But we'd have
already done LocalExecuteInvalidationMessage when getting out of
the prepared transaction, so no other SI invals should be needed.
