netfilter: ipset: allow a 0 netmask with hash_netiface type
Jozsef says:
The correct behaviour is that if we have
ipset create test1 hash:net,iface
ipset add test1 0.0.0.0/0,eth0
iptables -A INPUT -m set --match-set test1 src,src
then the rule should match for any traffic coming in through eth0.
This removes the -EINVAL runtime test to make matching work
in case packet arrived via the specified interface.
