[PATCH 14/20] netfilter: ipset: take into account cidr value for the from address when creating the set

From: Jozsef Kadlecsik <redacted>

When creating a set from a range expressed as a network like
10.1.1.172/29, the from address was taken as the IP address part and
not masked with the netmask from the cidr.
