Remove ethernet network enable.

[cecille]

Problem

On-network devices do not actually have to have their network enabled (they are already enabled by definition). An enable call to enable an ethernet network was added previously to kick the device into operational advertising as a workaround. Now that operational certificate provisioning puts the device into operational advertising mode, this is no longer needed.

Change overview

Remove EnableNewtork call with magic code.

Testing

Commissioned on-network device, saw no enable call, device properly finished provisioning and was visible on the network.
