RFR: 8315944: SunJCE provider should not zeroize the deserialized key values

Wed Sep 20 22:05:08 UTC 2023

This PR reverts part of the changes under JDK-8312306 which zero-out the deserialized key bytes after an internal copy has been made. If considering the deserialized key bytes as input arguments, such cleaning action may be too aggressive. Thus, on second thought, I am reverting to earlier behavior. No regression test since the changes are trivial.

Thanks!
Valerie
