With the objects layout security model we have object capabilities
that are associated with the layout ad we anticipate that the server
will issue a cb_layoutrecall for any setattr that changes security
related attributes (user/group/mode/acl) or truncates the file.
Therefore, the client returns the layout in advance to avoid the
extra layout recall.
