ocfs2: Stop orphan scan as early as possible during umount
Currently if the orphan scan fires a tick before the user issues the umount, the umount will wait for the queued orphan scan tasks to complete. This patch makes the umount stop the orphan scan as early as possible so as to reduce the probability of the queued tasks slowing down the umount.
