Michael Holzheu 5419447e21 Revert "s390/kdump: Clear subchannel ID to signal non-CCW/SCSI IPL" 
This reverts commit 852ffd0f4e23248b47531058e531066a988434b5.

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.
