lavfi/formats: more logical testing of inputs and outputs. 

ff_set_common_formats() is currently only called after
graph_check_validity(), guaranteeing that inputs and outputs
are connected.
If we want to support configuring partially-connected graphs,
we will have a lot of redesign to do anyway.

Fix CID 1466262 / 1466263.
