[PATCH v6 08/10] f2fs: Configure dentry operations at dentry-creation time

This was already the case for case-insensitive 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.

Since fscrypt now also supports configuring dentry operations at
creation-time, do it for any encrypted and/or casefold volume,
simplifying the implementation across these features.
