thunderbolt: Make usb4_switch_map_usb3_down() also return enabled ports

Browse Source 
We need to call this on enabled ports in order to find the mapping from
host router USB4 port to a USB 3.x downstream adapter, so make the
function return enabled ports as well.

While there fix parameter alignment in tb_find_usb3_down().
