netfilter: xt_recent: fix regression in rules using a zero hit_count
Commit 8ccb92ad (netfilter: xt_recent: fix false match) fixed supposedly false matches in rules using a zero hit_count. As it turns out there is nothing false about these matches and people are actually using entries with a hit_count of zero to make rules dependant on addresses inserted manually through /proc. Since this slipped past the eyes of three reviewers, instead of reverting the commit in question, this patch explicitly checks for a hit_count of zero to make the intentions more clear.
