Please review this fix for a ZGC shutdown/abort issue, introduced by JDK-8261759.
If a GC cycle has aborted, we should not notify that it completed and we should not check for out of memory condition. Doing so can cause pre-mature `OutOfMemoryError`.
- Tier 1-7 with ZGC on Linux/x86_64.
- Wrote a small reproducer that provokes the problem fairly quickly. With this patch, I can no longer reproduced the issue.
