net: ipv6: lower ndisc notifier priority below addrconf
ndisc_notify is used to send unsolicited neighbor advertisements (e.g., on a link up). Currently, the ndisc notifier is run before the addrconf notifer which means NA's are not sent for link-local addresses which are added by the addrconf notifier. Fix by lowering the priority of the ndisc notifier. Setting the priority to ADDRCONF_NOTIFY_PRIORITY - 5 means it runs after addrconf and before the route notifier which is ADDRCONF_NOTIFY_PRIORITY - 10.
