I check the output of `btrfs qgroup show ` command in the previous version, so I need a fixed nodesize. Now it is not necessary, I will update this patch and cc you.

Test if qgroup can handle extent de-reference during reallocation. "extent de-reference" means that reducing an extent's reference count or freeing an extent. Although current qgroup can handle it, we still need to prevent any regression which may break current qgroup.
