Subject: [PATCH 001 of 4] knfsd: Allow nfsd READDIR to return 64bit cookies


->readdir passes lofft_t offsets (used as nfs cookies) to
nfs3svc_encode_entry{,_plus}, but when they pass it on to
encode_entry it becomes an 'off_t', which isn't good.

So filesystems that returned 64bit offsets would lose.
