[PATCH] s390: device recognition

Close a small window where a device may be not operational again after senseid
finished and the "same device" check fails due to dev=0000 by checking for dnv
after stsch() by then setting the device to not operational.  (No need to
check for dnv in ccw_device_handle_oper() again since we don't do stsch() into
the subchannel's schib in the meantime and will get a crw anyway if the device
becomes not oper again).
