io_uring: move req->poll_refs into previous struct hole

This serves two purposes:

- We now have the last cacheline mostly unused for generic workloads,
  instead of having to pull in the poll refs explicitly for workloads
  that rely on poll arming.

- It shrinks the io_kiocb from 232 to 224 bytes.
