QUIC: always calculate rtt for largest acknowledged packet.
Previously, when processing client ACK, rtt could be calculated for a packet
different than the largest if it was missing in the sent chain. Even though
this is an unlikely situation, rtt based on a different packet could be larger
than needed leading to bigger pto timeout and performance degradation.
