drivers: hv: move device_to_hv_device to use container_of_const()

Browse Source 
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.
