blk-throttle: Fix io statistics for cgroup v1
After commit f382fb0bcef4 ("block: remove legacy IO schedulers"), blkio.throttle.io_serviced and blkio.throttle.io_service_bytes become the only stable io stats interface of cgroup v1, and these statistics are done in the blk-throttle code. But the current code only counts the bios that are actually throttled. When the user does not add the throttle limit, the io stats for cgroup v1 has nothing. I fix it according to the statistical method of v2, and made it count all ios accurately.
