iptables-nft: exit nonzero when iptables-save cannot decode all expressions

We always return 0, even if we printed some error message half-way.
Increment an error counter whenever an error message was printed so that
the chain-loop can exit with an error if this counter is nonzero.

Another effect is that iptables-save will no longer print the COMMIT line anmore.
