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.

I'm not sure if this is necessary, wouldn't mkfs.btrfs pick the proper
node/leaf size according to the platform at mkfs time?

Yes, you're right. 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.
