[PATCH] io_uring: flush deferred completions for multishot CQE32 posting

io_req_post_cqe() flushes compl_reqs before posting multishot CQEs
since commit 687b2bae0eff ("io_uring: ensure deferred completions are
flushed for multishot").  Apply the same flush to io_req_post_cqe32()
so both multishot aux posting helpers behave consistently.
