net/sched: cls_flower: Correct matching on ICMPv6 code
When matching on the ICMPv6 code ICMPV6_CODE rather than ICMPV4_CODE attributes should be used. This corrects what appears to be a typo. Sample usage: tc qdisc add dev eth0 ingress tc filter add dev eth0 protocol ipv6 parent ffff: flower \ indev eth0 ip_proto icmpv6 type 128 code 0 action drop Without this change the code parameter above is effectively ignored.
