devm_remove_action() warns if the action to remove does not exist (anymore). The Rust devres abstraction, however, has a use-case to call devm_remove_action() at a point where it can't be guaranteed that the corresponding action hasn't been released yet. In particular, an instance of `Devres<T>` may be dropped after the action has been released. So far, `Devres<T>` worked around this by keeping the inner type alive. Hence, add devm_remove_action_nowarn(), which returns an error code if the action has been removed already. A subsequent patch uses devm_remove_action_nowarn() to remove the action when `Devres<T>` is dropped.
