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.

o Minor bugfixes (scheduler, KIST):
|
|
- Avoid a possible integer overflow when computing the available space on
|
|
the TCP buffer of a channel. This has no security implications but can
|
|
make KIST not behave properly by allowing more cells on a already
|
|
saturated connection. Fixes bug 24590; bugfix on 0.3.2.1-alpha.
