openvswitch: Fixed nd target mask field in the flow dump.

Browse Source 
commit f19c44452b58a84d95e209b847f5495d91c9983a upstream.

IPv6 nd target mask was not getting populated in flow dump.

In the function __ovs_nla_put_key the icmp code mask field was checked
instead of icmp code key field to classify the flow as neighbour discovery.
