[PATCH BlueZ] src/device: Use BT_ATT_DEFAULT_LE_MTU as default MTU

Use the default MTU until an MTU exchange has taken place and
something else has been negotiated. If either side does not support
MTU exchange, the connection shall continue to use this default
value instead of the device maximum which was the previous behavior.
