In rare cases, the current non-recursive delete algorithm doesn't deallocate empty intermediary indirect blocks. This should have very little practical effect, but deallocating all blocks correctly should still be preferable as it is cleaner and easier to validate. The fix consists of using the first block to deallocate to compute the start marker of the truncate point instead of the last block that needs to be kept. With that change, computing which indirect blocks are still needed becomes relatively easy.
