net: fix netlink address dumping in IPv4/IPv6
When a dump is interrupted at the last device in a hash chain and then continued, "idx" won't get incremented past s_idx, so s_ip_idx is not reset when moving on to the next device. This means of all following devices only the last n - s_ip_idx addresses are dumped. Tested-by: Pawel Staszewski <pstaszewski@itcare.pl> Signed-off-by: Patrick McHardy <kaber@trash.net>
