Eric Biggers 8953430064 cryptfs: try harder to unmount subdirectory mounts 
ensure_subdirectory_unmounted() was ignoring the return value from
umount(), so it wasn't possible to tell whether it succeeded or failed.
Make it log an error message on failure.

Also, there might be cases where ensure_subdirectory_unmounted() fails
initially but would succeed later, e.g. due to files in a subdirectory
mount being open and requiring processes to be killed.  To make this
more robust, keep calling ensure_subdirectory_unmounted() before each
attempt of umount("/data").

I'm not sure whether this will actually fix bug 189250652, as it hasn't
been root-caused yet, but this might help.

Bug: 189250652
