zfs_scrub_limit tunable is not used anywhere

As a part of scrub/resilver tuning zfs_scrub_limit fell out of use, but the definition of the variable remained in place. Moreover various guides still (misleadingly) mention it as a way to influence resilver/scrub behavior. This commit removes its finally.
