[jdk17u-dev] RFR: 8321972: test runtime/Unsafe/InternalErrorTest.java timeout on linux-riscv64 platform

[Gui Cao]

Hi, The same issue also exists in the JDK17U: I can reproduce it locally by applying fix for JDK-8320886 and running test/hotspot/jtreg/runtime/Unsafe/InternalErrorTest.java test. So I would like to backport this to JDK17U. Tier1-3 tested with fastdebug build using qemu systems. This is a risc-v specific change, risk is low.
The backport is not clean because jdk17u-dev has no https://bugs.openjdk.org/browse/JDK-8301507.
