[PATCH net] net/sched: cls_flower: Correct matching on ICMPv6 code

[Simon Horman]

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.

code")
