Víctor Manuel Jáquez Leal 649c00d3c7 vaapipostproc: return caps template if no display 
This patch is a fix for my bad review of commit 6d73ca8d. The element should
be able to return the available raw caps handled by the VA display, but that
only should happen when there a VA display. If there's none, the element
should use the caps template.
