rG57317c8971df: tcp: exclude KASSERTS when rescue retransmissions are in play.
Summary

SACK rescue retransmission will inject a new scoreboard
hole beyond snd_fack, if a cummulative ACK with no further
SACK option is received before a SACK loss recovery has
completed (passed snd_recover).

The KASSERT criteria needs to be checked against the
sendbuffer so_snd in a subsequent version.
