rS336937: Send consistent SEG.WIN when using timewait codepath for TCP.
Summary

When creating a timewait entry, the last sent rcv window is stored. However, it is computed in a different way than in the main code path. This results in inconsistencies. These are fixed by using the same code as in tcp_output().

Test Plan

Run the attached packetdrill test.
