Hi. After previous fix I've reviewed sources a bit and found that
protocol and iface negated matches are broken in the same regard. Patch
in attachment fixes them too.

Fix restore of negated iface and proto matches
Attemt to restore ruleset with ! -i iface or ! -p proto matches fail
with the following error:
Using intrapositioned negation (`--option ! this`) is deprecated in
favor of extrapositioned (`! --option this`).
This patch fixes this issue.
