Before this CL, usb tethering in detail page doesn't have entitlement
check. This CL fix it by using the correct API
Also polish it by updating the UI before entitlement check to align
hotspot page. So in UI it will first check "usb tethering". If
entitlement check fail, it will revoke and go back to previous selection.
