drm: remove minor-id during unplug Don't delay minor removal to drm_put_minor(). Otherwise, user-space can still open the minor and cause the kernel to oops. Instead, remove the minor during unplug so any new open() will fail to access this minor. Note that open() and drm_unplug_minor() are both protected by the global DRM mutex so we're fine.
