Revert "From review: Cycles: use scene.views instead of render_result.views"

This reverts commit 43e10a6853e4659429d000225b93862708414b31.

render_result.views is already taken into account whether the views are enabled,
if they can be rendered (e.g., Stereo mode shows only left and right) and when
multiview is off, it has a "" fallback view.

Leaving it as it was for the time being.
