Michael Holzheu 852ffd0f4e s390/kdump: Clear subchannel ID to signal non-CCW/SCSI IPL 
For CCW and SCSI IPL the hardware sets the subchannel ID and number
correctly at 0xb8. For kdump at 0xb8 normally there is the data of
the previously IPLed system.

In order to be clean now for kdump and kexec always set the subchannel
ID and number to zero. This tells the next OS that no CCW/SCSI IPL
has been done.
