xfs: don't cross reference rmapbt with bitmaps if they're incomplete

Browse source

LOLLM points out that runtime errors (e.g. ENOMEM) when we're trying to
compute space usag bitmaps are silently dropped by the rmapbt scrubber.
We ought to flag that as an incomplete scrub instead of reporting
cross-referencing errors based on faulty data.
