s390/cio: unregister the subchannel while purging
The cio_ignore list is used to create and maintain the list of devices which is to be ignored by Linux. During boot-time, this list is adjusted and accommodate all the devices which are configured on the HMC interface. Once these devices are accessible, they are then available to Linux and set online. cio_ignore purge function should align with this functionality. But currently, the subchannel associated with the offline-devices are not unregistered during purge. Add an explicit subchannel-unregister function in the purge_fn callback.
