The "malformed control flow" assert now triggers regularly (see [JDK-8308392](https://bugs.openjdk.org/browse/JDK-8308392) and [JDK-8312980](https://bugs.openjdk.org/browse/JDK-8312980)). Let's disable it in JDK 21 to reduce the noise in the CI.

Thumbs up. Thanks for reducing the noise in the JDK21 CI!
