Timur Kristóf 0d527bb1aa ac/nir/cull: Change if condition for bounding box culling.
The previous code checked all_w_positive in the if condition.
Instead, always execute the bbox culling code and include
all_w_positive at the end.

We assume checking in the if is not beneficial because it's
very unlikely that there is no primitive in a wave whose W are
not all positive.

This allows moving other things to the condition
in the next commit.
