accel_perf: cycle tasks through task_pool 



When a task completes, always put it back in the task
pool (using TAILQ_INSERT_TAIL) and then use _get_task
to get a task for the next submission.  Currently this
will just allocate the task that was just put into
the TAILQ.  But an upcoming patch will allocate
more tasks than we have queue depth, and this patch
will ensure all of those tasks get used evenly.
