[PATCH 2/2] rust: drm: Remove unused flags argument from Registration::new()

[Danilo Krummrich]

The flags argument to drm_dev_register() is only passed to the
deprecated .load() callback. Rust DRM drivers always set this callback
to NULL, so the argument has no effect.

Remove the argument from drm::Registration::new(), pass zero to
drm_dev_register(), and update the Nova and Tyr callers.
