of: unittest: Cleanup partially-applied overlays
When of_overlay_fdt_apply() fails, the changeset may be partially applied, and the caller is still expected to call of_overlay_remove() to clean up this partial state. However, overlay_17 is the only test that takes care of cleaning up after an (expected) failure. Instead of adding cleanup code to each individual test, extend overlay_info with the optional expected return value of of_overlay_remove(), and handle cleanup in the overlay_data_apply() helper. While at it, simplify the end marker in the overlay_info table. Update the expected error output for errors during the newly cleanup.
