io_uring: add mshot helper for posting CQE32
Add a helper for posting 32 byte CQEs in a multishot mode and add a cmd
helper on top. As it specifically works with requests, the helper ignore
the passed in cqe->user_data and sets it to the one stored in the
request.
The command helper is only valid with multishot requests.
