tcp: Don't clear ACK_TO_TAP_DUE if we're advertising a zero-sized window
We correctly avoid doing that at the beginning of tcp_prepare_flags(),
but we might clear the flag later on if we actually end up sending a
"flag" segment.
Make sure we don't, otherwise we might delay window updates after a
zero-window condition significantly, and significantly affect
throughput.
In some cases, we're forcing peers to send zero-window probes or
keep-alive segments.
