This fixes two problems in the new provided buffer ring feature. One is a simple arithmetic bug (I think this came out from a refactor). The other is due to type differences between head & tail, which causes it to sometimes reuse an old buffer incorrectly. Patch 1&2 fix bugs Patch 3 limits the size of the ring as it's not possible to address more entries with 16 bit head/tail

I will send test cases for liburing shortly. One question might be if we should change the type of ring_entries to uint16_t in struct io_uring_buf_reg?
Why not? 5.19 is just rc2 now. So we can assume there is no users using it right now I think?
