viz: Fix params->background_texture == 0 case

In crrev.com/c/1296679 we removed unnecessary code given the assumption that
backdrop_texture could never be 0.

Unfortunately we missed the case where background_rect is empty, and we still
can have params->background_texture equal to 0.

This patch brings back that check.
