[jdk17u] RFR: 8278309: [windows] use of uninitialized OSThread::_state

[Thomas Stuefe]

Hi all,

I would like to backport this to jdk17. It fixes a potential error (even if it seems benign before JDK-8268773).

The commit being backported was authored by Thomas Stuefe on 8 Dec 2021 and was reviewed by David Holmes and Aleksey Shipilev.

Thanks!
