vp9-svc: Fix to compute some metrics on top spatiail layer. The avg_frame_low_motion and consec_zeromv are frame-level metrics that are updated on every frame. For SVC these should be updated on top spatial layer (full resolution). Small/negligible change in metrics. Change-Id: Ibe14f05be3b82daa9dd60378097ff11a27f1b95e
