vaapisink: return caps template if no display

Browse source 
If vaapisink received a caps query before getting a VA display, it returned
only the surfaces related caps. This behavior broke the autovideosink
negotiation.

This patch returns the pad's template caps if no VA display, otherwise the
caps are crafted as before.
