Please use qdev device-reset and bus-reset callbacks instead of this.
In particular, when writing the status you should call
qdev_reset_all(DEVICE(sch)), and whatever state should be reset will
have to be cleared by the device-reset callback of SubchDev, including
calling virtio_reset.
Everything else will be cleared instead by the bus-reset callback of
virtio-ccw-bus, similar to what you are doing in
virtio_ccw_reset_subchannels.
