8284094: Memory leak in invoker_completeInvokeRequest()

[gnu-andrew]

Hi all,

This pull request contains a backport of commit 1dfa1eae from the openjdk/jdk repository.

The commit being backported was authored by Roman Kennke on 1 Apr 2022 and was reviewed by Chris Plummer and Aleksey Shipilev.

This fixes a memory leak in the JDWP agent. It has baked in trunk for over a month and should now be safe enough to backport to stable releases.

Thanks!
