autofocus: Fix a crash with an autofocus element in a document without browsing context.

ShouldAutofocus() should check existence of the browsing context.
Otherwise, doc.TopFrameOrigin() returns null.

Before crrev.com/695830, ShouldAutofocus() was called only for
rendered elements. That is to say, the document always had
browsing context.
