RFR: 8251548 Remove unnecessary explicit initialization of volatile variables in security-libs code

[Сергей Цыпанов]

Hello,

is it possible to have a code review for the changes proposed in JDK-8251548 (originally contributed via
https://mail.openjdk.java.net/pipermail/security-dev/2020-June/022137.html)?

Sean Mullan has created an issue and web-review and can sponsor the patch as soos as it gets properly reviewed.

The issue itself is a continuation of changes merged into java.base before as:

- https://bugs.openjdk.java.net/browse/JDK-6736490
- https://bugs.openjdk.java.net/browse/JDK-8035284
- https://bugs.openjdk.java.net/browse/JDK-8145680

As Doug Lea claims in http://cs.oswego.edu/pipermail/concurrency-interest/2015-December/014770.html

> there is never any reason to explicitly initialize fields to 0/0.0/false/null

so I believe this patch is harmless as well as previous ones.

Issue: https://bugs.openjdk.java.net/browse/JDK-8251548
Webrev: https://cr.openjdk.java.net/~mullan/webrevs/8251548/

Thanks,
Sergey Tsypanov
