Fix off-by-one error in txid_status(). The transaction ID returned by GetNextXidAndEpoch() is in the future, so we can't attempt to access its status or we might try to read a CLOG page that doesn't exist. The > vs >= confusion probably stemmed from the choice of a variable name containing the word "last" instead of "next", so fix that too.
Back-patch to 10 where the function arrived.
