This has been asked a few times, so I ended up writing a blog entry on it http://marc.merlins.org/perso/btrfs/post_2014-04-26_Btrfs-Tips_-Cancel-A-Btrfs-Scrub-That-Is-Already-Stopped.html and in the end pasted all of it in the main wiki https://btrfs.wiki.kernel.org/index.php/Problem_FAQ#btrfs_scrub_will_not_start_nor_cancel Of course, this is really a stopgap until the cancel tool can realize that the scrub isn't really running anymore, and update the state file on its own.
