src: fix counter restoration
It was not possible to restore a ruleset countaining counter. The packets and bytes fields were not known from the parser but they were in the output of the list command. This patch fixes the issue by restoring correctly the counters if they are present in the command. Signed-off-by: Eric Leblond <eric@regit.org> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
