Comment (by nickm):

 I think the problem is that marked_circuit_free_cells doesn't remove the
 circuit from the active list.  One solution here is to just not do that
 assert, and allow channel_flush_from_first_active_circuit to skip empty
 circuits. Another is to make the circuit inactive when we remove its
 cells.  Both might be a good idea.
