NFS: Fake up 'wcc' attributes to prevent cache invalidation after write NFSv2 and v4 don't offer weak cache consistency attributes on WRITE calls. In NFSv3, returning wcc data is optional. In all cases, we want to prevent the client from invalidating our cached data whenever ->write_done() attempts to update the inode attributes.
