Joel Cunningham c31bd404e2 Fix unit test with assumed congestion avoidance
test_tcp_fast_rexmit_wraparound correctness relied on the congestion
window being in congestion avoidance so that only a single TCP_MSS
segment is sent upon ACKing the first segment.

It's not known whether the test was relying tcp_alloc() to set ssthresh
to 0 and thus start in congestion avoidance or if the test was working by
accident until changes in b90a54f989d0edafa36b29bb0c346d1b30e1bf8f

This fixes the test by enforcing the requirement of starting in
congestion avoidance
