it's wrong because our name cache is optional.
ie. a filesystem is free to choose not to use it at all.
please revert.

(besides, i don't think it works as linux procfs expects,
because there entries are not pinned.)

if vnode -> name translation is really necessary, it should be
implemented in upper layers.  (caller of VOPs, not filesystems.)
