    tcp: remove goto and address another NULL deref in SACK

    Missed another NULL dereference during KASSERTS after traversing
    the scoreboard. While at it, scratch the goto by making the
    traversal conditional, and remove duplicate checks using an
    unconditional loop with all checks inside.
