Clarify comment about SubresourceLoaderParams in the non-S13nServiceWorker case.

This comment seems outdated. S13nSW without NetworkService is
supported. The TODO is a bit vague about what was planned to be done.
I assume it was to merge the S13nSW without NetworkService code with
the non-S13nSW without NetworkService code, but there is not a viable
path for that, and as the code will be removed after S13nSW it's not
worth it.
