Instead of exposing the number that blk-throttle currently has
deferred, we can expose the number of bios that have been sent to
blk-throttle and the number of bios which left blk-throttle, both
monotically increasing and the difference indicating the number being
deferred. That way we can stick to the usual stats facility.

Thanks.
