RFR: 8310106: sun.security.ssl.SSLHandshake.getHandshakeProducer() incorrectly checks handshakeConsumers

[Jaikiran Pai]

Can I please get a review of this change which fixes the issue noted in https://bugs.openjdk.org/browse/JDK-8310106?

The commit here fixes the typo in `sun.security.ssl.SSLHandshake.getHandshakeProducer()` method to correctly use `handshakeProducers`.

I checked if a new jtreg test could be added for this, but given where this change resides and the nature of this change, I don't see a way to add one. Existing tests in `tier1`, `tier2` and `tier3` continue to pass with this change.
