Reduce unnecessary duplication when cancelling annotationLayer/xfaLayer rendering

Browse Source 
There's no good reason, as far as I can tell, to have `PDFPageView.reset` attempt to cancel `annotationLayer`/`xfaLayer` rendering in one special-case (this is mostly a leftover from older code). Previously cancelling was moved into the separate `PDFPageView.cancelRendering`-method, and by slightly tweaking the conditions there we're able to remove a bit of now unnecessary code from the `PDFPageView.reset`-method.
