> Need to update snapshot manager when applying editlog for deleting a

> Currently after deleting a snapshottable directory which does not have
> snapshots any more, we also remove the directory from the snapshottable
> directory list in SnapshotManager. This works fine when handling a delete
> request from user. However, when we apply the OP_DELETE editlog,
> FSDirectory#unprotectedDelete(String, long) is called, which does not contain
> the "updating snapshot manager" process. This may leave an non-existent inode
> id in the snapshottable directory list, and can even lead to FSImage
> corruption.
