Fix it will auto switch back to "No data transfer" after selecting "USB Tethering"

Before this CL, the USB option didn't handle whether FUNCTION_NCM
existed in the intent extra when tethering was started which resulted
in some devices that enable NCM will have incorrect UI.

This CL added a condition to check whether FUNCTION_NCM existed in the
intent extra or not to fix this UI issue.
