rfkill: add __must_check annotations
rfkill is not a small, mere detail in wireless support. Once it starts supporting rfkill and users start counting on that support, a wireless device is at risk of operating in dangerous conditions should rfkill support fail to properly activate. Therefore, add the required __must_check annotations on some key functions of the rfkill API, for which the wireless drivers absolutely MUST handle the failure mode safely in order to avoid a potentially dangerous situation where the wireless transmitter is left enabled when the user don't want it to.
