radioInterface: Rename mRadio to mDevice

Previous naming is ready confusing, because "Radio" is actually the
common term between radioInterface and radioDevice, and it looks like
it's referring to radioInterface rather than radioDevice. On the other
hand, mDevice cleary states it refers to the radioDevice item.
