tcp: Suppress knownConditionTrueFalse cppcheck false positive
cppcheck 2.10 reports:
tcp.c:1815:12: style: Condition 'wnd>prev_scaled' is always false [knownConditionTrueFalse]
if ((wnd > prev_scaled && wnd * 99 / 100 < prev_scaled) ||
^
tcp.c:1808:8: note: Assignment 'wnd=((1<<(16+8))<(wnd))?(1<<(16+8)):(wnd)', assigned value is less than 1
wnd = MIN(MAX_WINDOW, wnd);
^
tcp.c:1811:19: note: Assuming condition is false
if (prev_scaled == wnd)
^
tcp.c:1815:12: note: Condition 'wnd>prev_scaled' is always false
if ((wnd > prev_scaled && wnd * 99 / 100 < prev_scaled) ||
^
but this is not actually the case: wnd is typically greater than 1,
and might very well be greater than prev_scaled as well.
I bisected this down to cppcheck commit b4d455df487c ("Fix 11349: FP
negativeIndex for clamped array index (#4627)") and reported findings
at https://github.com/danmar/cppcheck/pull/4627.
Suppress the warning for the moment being.
