knfsd: fix callback rpc cred
It doesn't make sense to make the callback with credentials that the client made the setclientid with. Instead the spec requires that the callback occur with the credentials the client authenticated *to*. It probably doesn't matter what we use for auth_unix, and some more infrastructure will be needed for auth_gss, so let's just remove the cred lookup for now. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Acked-by: Neil Brown <neilb@suse.de>
