zipl: fix zfcp dump image location

The zfcp dumper fails with the following error:

MLOPDM003I: Machine loader finished, moving data to final storage
	    location.

	    uncompression error
--- System halted

HCPGIR450W CP entered; disabled wait
PSW 00020001 80000000 00000000 DEADBEEF

The zipl command shows overlapping components when installing the dumper
to a zfcp disk:

zipl -d /dev/sda1
Building bootmap directly on partition '/dev/sda1'
Adding dump section
  kernel image......: /lib/s390-tools/zfcpdump/zfcpdump-image

Preparing boot device: sda.
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.
