[S390] Fix reboot hang on LPARs
Reboot hangs on LPARs without diag308 support. The reason for this is, that before the reboot is done, the channel subsystem is shut down. During the reset on each possible subchannel a "store subchannel" is done. This operation can end in a program check interruption, if the specified subchannel set is not implemented by the hardware. During the reset, currently we do not have a program check handler, which leads to the described kernel bug. We install now a new program check handler for the reboot code to fix this problem.
