Instead of inserting a task into the TAILQ and then
immediately taking it back off, just pass the task
to bdevperf_submit_single instead.
This reduces overhead of bdevperf compared to nvme/perf.
nvme/perf does not use a TAILQ at all, and does something
similar by passing the just completed task so it can be
reused by its submit function.
