[8u] RFA 8187331: VirtualSpaceList tracks free space on wrong node

[Zhengyu Gu]

I would like to request a backport of this fix:

Bug: https://bugs.openjdk.java.net/browse/JDK-8187331
Changeset: http://hg.openjdk.java.net/jdk10/master/rev/198cb8e20aef
Review: 
http://mail.openjdk.java.net/pipermail/hotspot-runtime-dev/2017-September/024575.html

The patch applied cleanly with file path change.

Thanks,

-Zhengyu
