rfnoc: actions: Allow sending actions to self

Sending actions to self is useful because calling post_action() from
within an action handler will not actually trigger the action. Instead,
it will defer delivery of the action. Allowing sending actions to self
will allow to add another action, in deterministic order, and the
execution of another action handler.
