Title: Fixed NullReferenceException error if there's no record returned in ForwardsOnlyDataReader.UpdateOutputParameters

`row` variable is always used, so there's no benefit of lazy initialization. If there's no record returned, `ParameterUpdateRow` is `null` and `NullReferenceException` will be thrown at `(row = row ?? ParameterUpdateRow).NumFields`.
