io_post_aux_cqe(), which is used for multishot requests, delays completions by putting CQEs into a temporary array for the purpose completion lock/flush batching. DEFER_TASKRUN doesn't need any locking, so for it we can put completions directly into the CQ and defer post completion handling with a flag. That leaves !DEFER_TASKRUN, which is not that interesting / hot for multishot requests, so have conditional locking with deferred flush for them.
