    bluetooth: Avoid broken state when enabling Bluetooth
    
    When enabling Bluetooth, and with older versions of the rfkill
    gnome-settings-daemon D-Bus service, we could get into a state where the
    Bluetooth rfkill was off, but the hciX rfkill associated with the
    adapter is blocked.
    
    Avoid showing filler text in that case.
