SUNRPC: Replace svc_addr_u by sockaddr_storage
For IPv6 local address, lockd can not callback to client for
missing scope id when binding address at inet6_bind:
324 if (addr_type & IPV6_ADDR_LINKLOCAL) {
325 if (addr_len >= sizeof(struct sockaddr_in6) &&
326 addr->sin6_scope_id) {
327 /* Override any existing binding, if another one
328 * is supplied by user.
329 */
330 sk->sk_bound_dev_if = addr->sin6_scope_id;
331 }
332
333 /* Binding to link-local address requires an interface */
334 if (!sk->sk_bound_dev_if) {
335 err = -EINVAL;
336 goto out_unlock;
337 }
Replacing svc_addr_u by sockaddr_storage, let rqstp->rq_daddr contains more info
besides address.
