David Goulet 057139d383 sched: Avoid integer overflow when computing tcp_space
In KIST, we could have a small congestion window value than the unacked
packets leading to a integer overflow which leaves the tcp_space value to be
humongous.

This has no security implications but it results in KIST scheduler allowing to
send cells on a potentially saturated connection.

Found by #24423. Fixes #24590.
