[tcp] Avoid rewinding sequence numbers on receiving old duplicate ACKs
Commit 558c1a4 ("[tcp] Improve robustness in the presence of duplicated
received packets") introduced a regression in that an old duplicate
ACK received while in the ESTABLISHED state would pass through normal
ACK processing, including updating tcp->snd_seq.
Fix by ensuring that ACK processing ignores all duplicate ACKs.
