This is because, in the past, if the device in the subchannel is not working or not available, we used to unregister the subchannels. But, from the 'commit 2297791c92d0 ("s390/cio: dont unregister subchannel from child-drivers")' we allow subchannels with or without an active device connected on it. So, when we do the io_subchannel_verify, make sure that, we are evaluating the subchannels without any device too.
