Subject: [patch net-next] devlink: add missing unregister linecard notification

From: Jiri Pirko <jiri@...dia.com>

Cited fixes commit introduced linecard notifications for register,
however it didn't add them for unregister. Fix that by adding them.

Fixes: c246f9b5fd61 ("devlink: add support to create line card and expose to user")
