vaapipostproc: Don't create filter on caps query

Browse source 
The problem with this is that creating the filter causes the display to
be selected, and the caps query happens while linking the element. So,
if the downstream or upstream element is using a specific display
object, it won't be propagated correctly to the postproc as it already
has a display at this point.
