By the spec https://w3c.github.io/FileAPI/, FileReader.error should be DOMException now.

We don't need this local variable. This can be:
m_error = DOMException::create(e.exception());

> Source/WebCore/fileapi/FileReader.h:73
> +    RefPtr<DOMException> error() { return m_error; }

This should return a DOMException*, not need to ref:
DOMException* error() const { return m_error.get(); }

> Source/WebCore/fileapi/FileReader.idl:55
> +    readonly attribute DOMException error;

This should be:
readonly attribute DOMException? error;

As per spec, since it can return null.
