Zero-fill private_data when attaching an injection point InjectionPointAttach() did not initialize the private_data buffer of the shared memory entry before (perhaps partially) overwriting it. When the private data is set to NULL by the caler, the buffer was left uninitialized. If set, it could have stale contents.
The buffer is initialized to zero, so as the contents recorded when a point is attached are deterministic.
