[TCP]: tcp_rcv_rtt_measure_ts() call in pure-ACK path is superfluous
We only want to take receive RTT mesaurements for data bearing frames, here in the header prediction fast path for a pure-sender, we know that we have a pure-ACK and thus the checks in tcp_rcv_rtt_mesaure_ts() will not pass. Signed-off-by: David S. Miller <davem@davemloft.net>
