The wire's device is externally owned so reference/release were no-ops. To unify the code paths, remove the special casing and instead take an extra ref on the device the wire server is created with. This is functionally equivalent and will allow both the current wire code, and the incoming change to allow multiple device/adapter creation to both work. This CL also makes it possible for the client to destroy the device before child objects. A follow-up CL will mitigate this on the server side.
