Currently they are meant to be requeued down different path - never
down a path already used - so they try all paths then get

nothing is meant to be queued.
I think the bug is the goto requeue that should have tested
for m->suspended first - a test for queue_if_no_path missed when m
->suspended was added.
if (!m->queue_if_no_path &&!m->suspended) {
