When encoding a filehandle for a CB_NOTIFY, there is no svc_export available, but the server needs to know whether to encode a connectable filehandle. Add a flag to the nfs4_file that tells whether the svc_export under which a directory delegation was acquired has subtree checking enabled, in which case it needs connectable filehandles.
