udp_diag: implement idiag_get_info for udp/udplite to get queue information
When we use netlink to monitor queue information for udp socket, idiag_rqueue and idiag_wqueue of inet_diag_msg are returned with 0. Keep consistent with netstat, just return back allocated rmem/wmem size. Signed-off-by: Shan Wei <davidshan@tencent.com> Acked-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S.
