[S390] cio: fix unreg race in set_online path
In ccw_device_set_online we basically start path verification and wait for the device to reach a final state. If it turns out that the device has no useable path we schedule the deregistration of the device (which is still in an non-final state) and wake up the waiting process. The deregistration process will set a final state, but if the wake up happens to be prior to this, the device will hang forever in ccw_device_set_online. To fix this just set the final NOT_OPER state prior to the scheduled deregistration of the device.
