[DCCP] ACKVEC: Optimization - Do not traverse records if none will be found
Do not traverse the list of ack vector records [proportional to window size]
when we know we will not find what we are looking for. This is especially
useful because ack vectors are checked twice:
1) Upon parsing of options.
2) Upon notification of a new ack.
All of the work will occur during check #1. Therefore, when check #2 is
performed, no new work will be done. This is now "detected" and there is no
performance hit when doing #2.
