ONOS has incorrect OVS driver when running on BM

This problem only occurs on BM cluster and not on VMs.

To replicate:
1) start a simple linear topo, e.g. 5 switches; start onos as single of multiple nodes;
2) onos would not discover the whole topo.
3) upon inspection, we see the first two switches have incorrect driver (ofdpa-cpqd) activated.
