msdasql: Always return affected rows if required.

When using msadosql it always returns the number of records
affected or records returned by a SELECT statement.

The access database, which is what the defaults tests are using
doesn't return the number of records for a SELECT.
It's a known issue that you have to MoveLast/MoveFirst before
the correct RecordCount value is return for an Access DB.
