Run comparison code if the data migration finished with fallback

If the data migration process runs finished with fallback,
that means we might get some unknown data that cannot be handled
by importing code.

If that happens, the CL runs the problematic code whenever device
boot-up but doesn't do the actual import process. This improves the
debuggability since the current log disappears after device reboot,
which will show up in every boot-up log after this CL.
