From: K. Y. Srinivasan <kys@xxxxxxxxxxxxx>
Both device abstractions: vm_device and hv_device maintain state
to reperesent the device instance (and they refer to them by different
names - device_id in vm_device and dev_instance in hv_device).
In preparation for consolidating all device state in
struct hv_device; eliminate device_id from struct vm_device.
