When we configured bond that use recirc and configure mirror, we
observed that mirror destination has duplicated outputs.  This is
because bond's frozen_state is not updated to reflect the mirror
already composed the output, and when the companion recirc flow
need to decide its action, the mirror again take effects, causing
duplicate outputs.
