The NS_ERROR is just wrong, but to get right behavior after bug 675166 is fixed,
we should use GetOwnerDocument.

Why this change? This is slightly slower. Not that it matters perf wise, but doesn't seem like a win either.

Because after bug 675166 GetOwnerDoc() will actually return something in this case, 
and we don't actually want that something but null.

But ok, if DOM Core has changed, this patch is wrong.

So, the spec has changed and this will be fixed in the bug which makes
GetOwnerDoc to return always a valid value.

Fixed in bug 675166
