All dentries in a case-insensitive filesystem have the same set of dentry operations. Therefore, we should let VFS propagate them from sb->s_d_op d_alloc instead of setting at lookup time. This was already the case before commit bb9cd9106b22 ("fscrypt: Have filesystems handle their d_ops"), but it was changed to set at lookup-time to facilitate the integration with fscrypt. But it's a problem because dentries that don't get created through ->lookup() won't have any visibility of the operations. Let's revert to the previous implementation.
