As a followup: the sb-downgrade patch was good, the user had at some
point been running an unreleased version (which adds new accounting for
amount of unstriped data in stripe buckets); and that version generated
a faulty downgrade entry (because it has custom logic for generating the
downgrade entry based on whether erasure coding is in use).

But I'm still holding that patch for now while I come up with something
for that user's filesystem - I'll probably add a flags parameter to that
validation code so that we only fail to validate if we're writing out
something new, like we already can for bkeys.
