RFR: 8303681: JFR: RemoteRecordingStream::setMaxAge() should accept null [v2]

[Erik Gahlin]

> Could I have a review of a PR that removes a Objects.requireNonNull from the setMaxAge method in the RemoteRecordingStream class. The check was accidentally added when the class was introduced in JDK 16. The specification states that null is accepted (similar to the Recording class). Max age is by default null, but can be set to another duration, for example Duration.ofHours(1), but not set back to null without this change.
