vp9-svc: Fix to resetting RC for temporal layers

Fix to reset RC for temporal layers: the
first_spatial_layer_to_encode is usually/default 0,
so the logic to reset for temporal layers was not
being executed. Use VPXMAX(1, ) to make sure  all
temporal layers will be reset (when max-q is used
for overshoot).
