zephyr: warn on boot if flash areas are still open

Add reference counting to the flash areas, and a zephyr-only routine
which warns when areas are still open when none should be. Call the
warn routine right before chain-loading.

This prints warnings due to code in loader.c. Future work will be
needed to clean this up.
