Implement compute_stats() in terms of devstat_compute_statistics(). This
gets rid of the duplicated code in compute_stats().
Add a new DSM_SKIP statistic type for devstat_compute_statistics() that
causes the subsequent variable argument to be skipped.
Thanks to Sergey Osokin for coding up my idea/code fragment.
