doc: `error` event is optionally emitted after `.destroy()`

error event on each kind of stream is optionally emitted when .destroy() method is called. It depends on ._destroy() implementation. In default implementation this event will no be fired unless error parameter has been provided.

It was already mentioned for writable.destroy([error]), so I just copied same sentence for the other streams.
