xattr isn't necessary. The code lingers because previously we use it to do
refcount for deletion.

I think of removing these xattr code, since 'cluster snapshot' doesn't use it
at all for now. You can actually move snapshot everythere you want. The cluster
snapshot is location independent.

Stay tuned I'll remove xattr dependency and then you can save cluster snapshot
directly on your SBM share.
