rrunner: fix buffer overflow
tx_skbuff is define as: struct sk_buff *tx_skbuff[TX_RING_ENTRIES]; EVT_RING_ENTRIES is 64 and TX_RING_ENTRIES is 32. This function is in a error path so that's why it wasn't noticed. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
