Issue: ether_get_ptptime() is registered as a callback
function to read ptp time using tegra_register_hwtime_source.
But it is not unregistered before interface is brought down.
This causes clients to still query for timestamp even though
interface is down and MAC is in reset, resulting in CBB errors.
Fix: Unregister the callback function in ether_close()
