block: Change bitmap truncate conditional to assertion
This is an artifact of an older version that had both all-bitmap and single-bitmap truncate functions, and some info got lost in the shuffle. Bitmaps can only be frozen during a backup operation, and a backup operation should prevent a resize operation, so just assert that this cannot happen.
