netstack: don't ACK SYNs in TIME-WAIT
It was possible for a SYN to arrive after the endpoint sent an ACK as part of
the transition to TIME-WAIT, but before returning from handleSegmentsLocked().
This caused the SYN to be dequeued and ACK'd despite the change in
EndpointState.
Deflakes TestTCPTimeWaitNewSyn.
Tested with:
blaze test --config=gotsan --runs_per_test 10000 \
//third_party/gvisor/pkg/tcpip/transport/tcp:tcp_x_test -j 2000 \
// --test_filter TestTCPTimeWaitNewSyn
