The ucsi_psy_get_current_max function defaults to 0.1A when it is not
clear how much current the partner device can support. But this does
not check the port is connected, and will report 0.1A max current when
nothing is connected. Update ucsi_psy_get_current_max to report 0A when
there is no connection.
Fixes: af833e7f7d ("usb: typec: ucsi: psy: Set current max to 100mA for BC 1.2 and Default")
