Fix bug: sometimes valid entries in hash:* types of sets were evicted
Wrong index was used and therefore when shrinking a hash bucket at deleting an entry, valid entries could be evicted as well. Thanks to Eric Ewanco for the thorough bugreport. Fixes netfilter bugzilla #1119 Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
