pnfs: layoutret_on_setattr
With the objects layout security model, we have object capabilities
that are associated with the layout and 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 layout is returned before issuing the setattr to avoid
the anticipated cb_layoutrecall.
