Cycles: Fix uninitialized number of hits

Was happening when looking for all intersections for transparent shadow rays
in the case the ray is degenerate.

Still quesitonable whether we should consider this a transparent or opaque
configuraiton. Ideally, we should prevent such rays from happening, but that
is another vector of debugging.
