vaapipostproc: notify if src pad caps changed

Browse source 
If src pad caps have changed, it needs to notify it downstream. In
addition, do not set passthrough if they have changed.

Otherwise, transform sometimes starts processing before caps change.
The passthrough value will be set in fixate later in this case.
