acer-wmi: check the existence of internal wireless device when set capability
That will be better to check the existence of internal wireless device
when we set wireless capability and generate killswitch for it. It can
avoid userland access wireless rfkill but the machine doesn't have internal
wireless device.
Tested on Acer Travelmate 8572
