Not that you can request a >2GiB transaction, but that's why checking for it makes no sense anymore. With the newer 'limit' parameter to prepare_buf, we no longer need a static limit. The maximum limit is still 2GiB, but the limit parameter is set to the current transaction size, which cannot surpass 32MiB (512 * 65536). If the PRDT surpasses the transactional size, then, we'll just carry out the normative underflow handling pathways instead of needing an extra, strange pathway that worries about hitting some logistical cap for the largest sglist we can support -- we'll never even attempt to build one that big anymore.
