Invalidate NN interface objects on cache mismatch
Currently, if an IDevice object is a DEAD_OBJECT, the runtime attempts
to re-retrieve the handle to the rebooted IDevice service. If an update
occurs after the IDevice was originally created, the rebooted IDevice
object may have different metadata and behavior. This is problematic
because the original metadata is cached in the runtime. Further, an
application might have made decisions based on that metadata and
behavior. (Note that a driver service that is functionally the same but
has a different underlying implementation such as having more optimized
code will have different `getVersionString` metadata.) Instead, this CL
invalidates the IDevice object on cache mismatch, and always returns an
error if it is used.
