ofproto-dpif-xlate: Put recirc_state, not recirc_id_node, in xlate_in.
This will make it possible, in an upcoming commit, to construct a
recirc_state locally on the stack to pass to xlate_actions(). It would
also be possible to construct and pass a recirc_id_node on the stack, but
the translation process only uses the recirc_state anyway. The alternative
here of having upcall_xlate() know that it can recover the recirc_id_node
from the recirc_state isn't great either; it's debatable which is the
better approach.
