I think it's debatable whether this change is correct or not. The callback is not a requirement to closing a stream and this can introduce a resource leak for someone that might be handling this type of error via a domain or an uncaughtException (as dubious as that is). It's also worth noting that the existing version matches other usage in the codebase where a callback is only provided as an event notification mechanism.

@apapirovski the code is called synchronously from user code. If there a wrong value as a callback they need to crash. The alternative here is that if it's not a function it gets skipped,
as its done in streams (https://github.com/nodejs/node/blob/master/lib/_stream_writable.js#L273-L274).

I think we should validate synchronously when close() is called, and in case validation of that parameter fail we might decide either to throw or to replace it with a function() {}. I think throwing leads to better code.

Anyway, are you objecting?

Should this be backported to v9.x-staging? If yes please follow the guide and raise a backport PR, if not let me know or add the dont-land-on label.
