This reverts commit 5b7048b89745c3c5fb4b3080fb7bced61dba2a2b. The throtl_adjusted_limit function was removed after commit bf20ab538c81 ("blk-throttle: remove CONFIG_BLK_DEV_THROTTLING_LOW"), so the problem of not being able to scale after setting bps or iops to 1 will not occur. So revert this commit that bps/iops can be set to 1.
