odhcp6c: apply IPv6/ND configuration earlier

Browse Source 
Apply IPv6/ND configuration before proto_send_update so that all config info
is available when netifd is handling the notify_proto ubus call.
In particular this fixes an issue when netifd is updating the downstream IPv6 mtu
as netifd was still using the not yet updated upstream IPv6 mtu to set the
downstream IPv6 mtu
