Change log level to debug for migrations pairing

For resize/cold-migration it's possible that instance
already changed host to destination, but no confirm/revert
has happened yet. In that case resource tracked starts spamming
errors, because it's impossible to match migration and instance.
It's safe to lower log level to debug in that case.
