In case we received no data on the call to skb_recv_datagram(), i.e. skb->data is NULL, vmci_transport_dgram_dequeue() will return with 0 without updating msg_namelen leading to net/socket.c leaking the local, uninitialized sockaddr_storage variable to userland -- 128 bytes of kernel stack memory. Fix this by moving the already existing msg_namelen assignment a few lines above.
