CLEANUP: http: explicitly reference request in http_apply_redirect_rules()

This function was made to perform a redirect on requests only, it was
using a message or txn->req in an inconsistent way and did not consider
the possibility that it could be used for the other direction. Let's
clean it up to have both a request and a response messages.
