  Add a vput() to nfs_lookitup() in the experimental NFS client
  for a case that will probably never happen. It can only
  happen if a server were to successfully lookup a file, but not
  return attributes for that file. Although technically allowed
  by the NFSv3 RFC, I doubt any server would ever do this.
  However, if it did, the client would have not vput()'d the
  new vnode when it needed to do so.
