Description

In INodeDirectory#replaceSelf4Quota, we convert the target node to INodeDirectoryWithSnapshot when the latest snapshot is not null. This may convert a directory, which was created after taking the latest snapshot, to an INodeDirectoryWithSnapshot. We thus should use INode#isInLatestSnapshot for checking here.
