etnaviv: only flush resource to self if no scanout buffer exists

Currently a resource flush may trigger a self resolve, even if a scanout buffer
exists, but is up to date. If a scanout buffer exists we only ever want to
flush the resource to the scanout buffer. This fixes a performance regression.
