The current code does not fill the msg_name member in case it is set. It also does not set the msg_namelen member to 0 and therefore makes net/socket.c leak the local, uninitialized sockaddr_storage variable to userland -- 128 bytes of kernel stack memory. Fix that by simply setting msg_namelen to 0 as obviously nobody cared about iucv_sock_recvmsg() not filling the msg_name in case it was set.
