The software eventdev can lock-up if not all queues are
linked to a port. For this reason, the software evendev
fails to start if queues are not linked to anything.

This commit creates dummy links from all queues to port
0 in the eventdev setup function and start/stop test,
which would otherwise fail due to unlinked queues.
