of: overlay: Make node skipping in init_overlay_changeset() clearer
Make it more clear that nodes without "__overlay__" subnodes are skipped, by reverting the logic and using continue. This also reduces indentation level. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Rob Herring <robh@kernel.org>
