nfsd: restrict filehandles accepted in V4ROOT case
On V4ROOT exports, only accept filehandles that are the *root* of some
export. This allows mountd to allow or deny access to individual
directories and symlinks on the pseudofilesystem.
Note that the checks in readdir and lookup are not enough, since a
malicious host with access to the network could guess filehandles that
they weren't able to obtain through lookup or readdir.
