devres: add devm_remove_action_nowarn()

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.
