tcp: tsq: add a shortcut in tcp_small_queue_check() Always allow the two first skbs in write queue to be sent, regardless of sk_wmem_alloc/sk_pacing_rate values. This helps a lot in situations where TX completions are delayed either because of driver latencies or softirq latencies. Test is done with no cache line misses.
