pd: fix superspeed mux steering on UFP
When the device has a USB superspeed UFP (which is uncommon, this is
either servo v4.1 or a laptop port in SS device-mode), if we connect as
a sink *before* trying PD communication, we should connect the SS mux
without waiting for the partner PD comm capability as we might never be
able to communicate with it over PD.
