NFS: Guard against READDIR loop when entry names exceed MAXNAMELEN
Commit 64cfca85bacd asserts the only valid return values for
nfs2/3_decode_dirent should not include -ENAMETOOLONG, but for a server
that sends a filename3 which exceeds MAXNAMELEN in a READDIR response the
client's behavior will be to endlessly retry the operation.
We could map -ENAMETOOLONG into -EBADCOOKIE, but that would produce
truncated listings without any error. The client should return an error
for this case to clearly assert that the server implementation must be
corrected.
Fixes: 64cfca85bacd ("NFS: Return valid errors from nfs2/3_decode_dirent()")
