adapter: pass follower direction to converter

Partially revert 86af9de739

The PortParam does not give enough information to derive the direction
of the converter. If the converter is configured in convert/convert
there is just no way to know when to output a quantum or not.

Fix this by doing a quick probe of the follower and then pass the
direction to the converter.
