Details:

I have noticed, that sometimes ACK packets include SACKs for data that is
before the ACK in the same packet (meaning it was SACKing data already
delivered in-order).
Turns out the SACK ranges were cleared before final modifications in ooseq
queue after new packet delivery.
This patch fixes that.
