l2tp: fix info leak in l2tp_ip6_recvmsg()
[ Upstream commit b860d3cc62877fad02863e2a08efff69a19382d2 ]
The L2TP code for IPv6 fails to initialize the l2tp_conn_id member of
struct sockaddr_l2tpip6 and therefore leaks four bytes kernel stack
in l2tp_ip6_recvmsg() in case msg_name is set.
Initialize l2tp_conn_id with 0 to avoid the info leak.
