Addresses coverity scan issue 55489

The existing tests pass but I did not add any new tests. I did not see any existing tests around error handling of openssl functions nor any test harness to allow you to do so.

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • tests and/or benchmarks are included
  • commit message follows commit guidelines

I must be missing something b/c when I review the output of test/arm I don't see a failure...

@tmeisenh It's an issue with the github bot that sends the results back, if it's green on ci.nodejs.org (which it is), then CI passed.

CI is green

LGTM but the commit log's status line should be <= 50 characters.

@gibfahn Awesome, thanks for the explanation.
@bnoordhuis nice catch on the commit log exceeding the recommended length. I can alter that if necessary.

If you wouldn't mind amending the commit message, you'll save whoever lands this a few keystrokes. But if you don't update it, whoever lands it can update it for you, so either way, really.

Looks like it can only occur with engines: openssl/openssl@87d52468aa600e023, so untestable.

OK, debugged, it does look the digests return 1 on success, and always do this for software digests, so LGTM

Running CI again only because the pushing of the amended commit message theoretically may have accidentally included a code change or something. Just being thorough.

CI: https://ci.nodejs.org/job/node-test-pull-request/5968/
