Stefan Haberland 96aca84128 s390/dasd: prevent inconsistent LCU device data ... commit a29ea01653 upstream. Prevent _lcu_update from adding a device to a pavgroup if the LCU still requires an update. The data is not reliable any longer and in parallel devices might have been moved on the lists already. This might lead to list corruptions or invalid PAV grouping. Only add devices to a pavgroup if the LCU is up to date. Additional steps are taken by the scheduled lcu update.
