tcp: Don't limit window to less-than-MSS values, use zero instead
If the sender uses data clumping (including Nagle's algorithm) for
Silly Window Syndrome (SWS) avoidance, advertising less than a MSS
means the sender might stop sending altogether, and window updates
after a low window condition are just as important as they are in
a zero-window condition.
For simplicity, approximate that limit to zero, as we have an
implementation forcing window updates after zero-sized windows.
This matches the suggestion from RFC 813, section 4.
