Kinglong Mee 3967cf7e6a nfsd: map the ENOKEY to nfserr_perm for avoiding warning 
commit c952cd4e94 upstream.

Now that Ext4 and f2fs filesystems support encrypted directories and
files, attempts to access those files may return ENOKEY, resulting in
the following WARNING.

Map ENOKEY to nfserr_perm instead of nfserr_io.
