Bug description:
  Bug present in ENA since driver version 1.6; manifests as a crash only
  under some conditions.

  In ena_remove() we have the following stack call:
      ena_remove()
        unregister_netdev()
        ena_destroy_device()
          netif_carrier_off()
      
  Calling netif_carrier_off() causes linkwatch to try to handle the
  link change event on the already unregistered netdev, which leads
  to a read from an unreadable memory address.
