Overlayfs introduces some complexity with regards to what path we have to use to shut down the scratch filesystem: it's SCRATCH_MNT for regular filesystems, but it's OVL_BASE_SCRATCH_MNT (i.e. the lower mount of the overlay) if overlayfs is enabled. The helper works through all that, so we might as well use it. Signed-off-by: Darrick J.
