kexec: remove never used member destination in kimage
struct kimage has a member destination which is used to store the real destination address of each page when load segment from user space buffer to kernel. But we never retrieve the value stored in kimage->destination, so this member variable in kimage and its assignment operation are redundent code. I guess for_each_kimage_entry just does the work that kimage->destination is expected to do. So in this patch just make a cleanup to remove it. Signed-off-by: Baoquan He <bhe@redhat.com> Cc: "Eric W.
