The zfcp dumper fails with the following error:
MLOPDM003I: Machine loader finished, moving data to final storage
location.
uncompression error

The zipl command shows overlapping components when installing the dumper
to a zfcp disk:
zipl -d /dev/sda1

Done.
With the secure IPL patchset the offset of the kernel image has been
removed for the normal IPL case but it has not been removed for the dump
image which leads to the overlap of 0x10000.
Fix by removing the offset for the dump case.
