In `inline` submit mode, threads wait until all previous IOs finish upon reaching rate limits, which may exceed the expected wait time and result in batch or uneven submissions. Handle completion events in usec_sleep() when necessary and no longer call io_u_quiesce() before sleeping in rate_ddir() to achieve smoother fix-rate submission as in `offload` mode.
