Fixing a NullPointerException in Neutron Interface (Bug-323)
Ideally, this condition should never occur. But there seems to be a consistency issue in the ML2 driver
which could potentially result in this condition. While we are addressing the root-cause in ODL ML2
driver, we should also patch our side of the interface as well to avoid failing for such conditions when
it is harmless for a few usecases.
