Processing Hwvtep/Ovsdb client only once
There are chances of same client is getting processed multiple times
and resulting in stale eos entry in one controller.
Due to this stale eos entry in controller1 if the device is getting
connected to controller2 it could not be processed as controller1 still
remains as eos leader for this device.
Ideally controller1 should have released its ownership when the device is
disconnected.
