zipl: Fix entry point for stand-alone kdump

Browse Source 
Currently zipl doesn't differentiate between the load address and the
entry point of an image, causing stage3 to strip away the entry point at
0x10000 for stand-alone kdump. This breaks the kdump kernel as it jumps
to 0x10000 after the special handling needed for kdump has been
performed.

Fix this by differentiating between the load address and the entry point
of an image.

Fixes: d142fbd5 ("zipl: Do not strip kernel image IPL header")
