Update the InnoDB internal auto-inc counter in ::write_row() if the statement is a REPLACE that fails in a duplicate key error: REPLACE will handle duplicate key error, and the insert will eventually succeed; note that we did NOT change InnoDB's behavior in an UPDATE, because updating the auto-inc counter in an UPDATE would require a bigger patch (Bug #11005)
