Michael Holzheu 4cf8f0b0b3 Revert "s390/kdump: Clear subchannel ID to signal non-CCW/SCSI IPL" 
commit 5419447e21 upstream.

This reverts commit 852ffd0f4e.

There are use cases where an intermediate boot kernel (1) uses kexec
to boot the final production kernel (2). For this scenario we should
provide the original boot information to the production kernel (2).
Therefore clearing the boot information during kexec() should not
be done.
