MMC_QUIRK_BLK_NO_CMD23 does *not* tell us whether the card support CMD23. Instead it tells us that the card may suffer a bit from performance point of view while using the "CMD23 way" to send requests. Now, as reliable write needs to be sent in the "CMD23-way", then that's what we need to do - no matter of MMC_QUIRK_BLK_NO_CMD23.
