shutdown: teardown loop devices only after umount
This still isn't really ideal, but attempting to detach loops while they're still mounted will definitely fail. Ideally, the loop device is in autoclear mode and dropping its refcount to 0 on umount will cause the backing file to be detached from the loop. Of course, this all gets way too complicated for userspace to handle when dealing with the sort of rat's nest of loop devices that ArchISO sets up. The kernel doesn't help us out here by populating things like holders/ and slaves/, but I'm not sure it could. Maybe there's a better way... Signed-off-by: Dave Reisner <dreisner@archlinux.org>
