drivers: hv: move device_to_hv_device to use container_of_const()
The driver core is changing to pass some pointers as const, so move device_to_hv_device() to use container_of_const() to handle this change. device_to_hv_device() now properly keeps the const-ness of the pointer passed into it, while as before it could be lost.
