RFR: 8300024: Replace use of JNI_COMMIT mode with mode 0

[Daniel Jeliński]

Please review this patch that fixes a few memory leaks in JNI code.

[The latest documentation](https://docs.oracle.com/en/java/javase/17/docs/specs/jni/functions.html#releaseprimitivetypearrayelements-routines) of JNI functions makes an explicit note about the use of JNI_COMMIT:

> If `JNI_COMMIT` is passed as the `mode` argument when `elems` is a copy of the elements in `array`, then a final call to *Release<PrimitiveType\>ArrayElements* passing a `mode` argument of "0" or `JNI_ABORT`, should be made to free the `elems` buffer

No new regression test. I manually verified the Linux fix using ClhdsbPstack test in root mode. Also, tier1-2 tests on mach5 continue to pass.
