    rfkill: Do not sync state immediately when opening rfkill
    
    We are opening the device asynchronously anyway. There is really no need
    to sync the state immediately, we can simpl rely on the POLL handler to
    do so later on from the mainloop.
    
    The difference we should see is that the debug information about there
    being no rfkill devices is gone. And, that some of the debug messages
    will be slightly different.
