ipv6: honor ifindex in case we receive ll addresses in router advertisements
Marc Haber reported we don't honor interface indexes when we receive link local router addresses in router advertisements. Luckily the non-strict version of ipv6_chk_addr already does the correct job here, so we can simply use it to lighten the checks and use those addresses by default without any configuration change.
