Fix infinite recursion in OpenVG scissor-only clipping
When a complex transform was set, clip(QVectorPath) would call clip(QRect) with the control point rect, which would then turn around and say "transform is complex, call clip(QVectorPath)", causing an infinite loop until stack crash. Remove the "fall back to vector path" case as it isn't useful for scissor-only clipping. Doesn't affect mask-based clipping. Reviewed-by: Sarah Smith
