Early out in OnFocusedNodeChanged if there's no view.

Early out in OnFocusedNodeChanged if there's no view.

The function RenderViewHostImpl::OnFocusedNodeChanged() currently
crashes if there's no view, which is a possibility (see check near
top of function). This CL adds an early out to avoid the crash.
