Unmounting a fileystem mounted on a loop device doesn't always tear down the loop device. Its racy, and it causes tests to randomly fail. To avoid that, we have to use umount -d to ensure that we destroy loop devices under filesystems in case the kernel doesn't tear it down automatically to prevent the test from failing. However, if the kernel does tear it down automatically, umount now issues a warning that it couldn't tear down the loop device because it couldn't find it, and that causes the test to fail. *facepalm* So, convert all the loop device unmounts to use -d, and direct the output of all of them to /dev/null.
