ipv6: anycast: complete RCU handling of struct ifacaddr6
struct ifacaddr6 are already freed after RCU grace period.
Add __rcu qualifier to aca_next pointer, and idev->ac_list
Add relevant rcu_assign_pointer() and dereference accessors.
ipv6_chk_acast_dev() no longer needs to acquire idev->lock.
/proc/net/anycast6 is now purely RCU protected, it no
longer acquires idev->lock.
Similarly in6_dump_addrs() can use RCU protection to iterate
through anycast addresses. It was relying on a mixture of RCU
and RTNL but next patches will get rid of RTNL there.
