fix when there is no adaptor for an instance.

PS: I couldn't test it as my machine does not have a hw switch to turn
bluetooth off... and I'm lazy to search how to disable it using
software (hciconfig hci0 down does not do it, just put the adapter in
offline mode and my btusb is not modular, so I can't remove the
module) :-)
