tcp/sack: If other side reneged, discard the current SACK scoreboard
Other side reneging is detected using the first SACK record:
If its left edge is less than or equal to the cumulative ACK of the
incoming segment, other side probably reneged.
This fixes the later assertion that the first SACK record's left edge
must be above snd_una in tcp_sack_first_unsacked_len()
Add statistics about other side reneging
