15 years agomds: fix trim_dentry on dentry under unlinked dir

We can get a dentry that is trimmable (e.g. null) under a new unlinked dir,
which has no subtree.  This will only happen on the auth.  In that case,
having no container is harmless--it's only needed for replicas.

This fixes the following crash:
