XXX: Temporary work around to fdesc truncating files when it shouldn't. Treat

setattr calls on underlying vnodes the same as sockets and just return 0.

This whole thing needs to be gutted and replaced with either fall throughs
to specfs (the attr forwarding is just bizarre and leads to weird crap like
the above truncation problems), or better yet a real cloning device node.
