Memset the control block to zeroes before calling skb_segment

skb_segment casts part of skb->cb to some structure to determine
tunnel header length. Having remnants of packet structure in cb
results in wrong tunnel header length calculation and thus wrong
memory copies to random memory locations. This problem is with
newer kernels (4.x).
