NFS: Secure the roots of the NFS subtrees in a shared superblock
Invoke security_d_instantiate() on root dentries after allocating them with
dentry_alloc_anon(). Normally dentry_alloc_root() would do that, but we don't
call that as we don't want to assign a name to the root dentry at this point
(we may discover the real name later).
