xtables: Make 'iptables -S nonexisting' return non-zero

To be consistent with legacy iptables, calling -S with a non-existing
chain should lead to an error message. This is how some scripts find out
whether a user-defined chain exists or not.

Make sure doing the same for an existing chain does succeed, even if an
invalid rule number was given.
