rGac83f3fa44f3: tcp: properly unroll SACK transmission on TX error with LRD
rGe3b9058e5cd0: tcp: properly unroll sack transmission on tx error with LRD
Summary

While going over the code looing at PR275798, I spotted that
with LRD the rewind of the sackhole retransmission pointer
would not necessarily be calculcated correctly. In particular
with LRD, we point to snd_recover when a hole is fully retransmitted.
Need to account for that in case of a local transmission error.
