3.1-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 7011687f0f2f12cc348f6a693fafe63d89167eac ]
in func icmp6_dst_alloc,dst_metric_set call ipv6_cow_metrics to set metric. ipv6_cow_metrics may will call rt6_bind_peer to set rt6_info->rt6i_peer. So,we should move ipv6_addr_copy before dst_metric_set to make sure rt6_bind_peer success.
