[PATCH v3 10/15] NTB: ntb_test: Update ntb_tool DB tests

DB interface of ntb_tool driver hasn't been changed much, but db_valid_mask DebugFS file has still been added. In this case it's much better to test all valid DB bits instead of using the predefined mask, which may be incorrect in general. Signed-off-by: Serge Semin ---
