fail *hard* if TrafficController::start() fails

Hitting this abort() likely means map initialization failed,
and basically things won't work correctly.

Another possibility detected on wembley is a kernel bpf bug
which prevents writes into index != 0 of bpf array maps.

But such a kernel bug will make TC useless.
Best to abort() and cause a mainline module rollback.
