This patch is to avoid potential issue when we still use the pointer images->legacy_hdr_os after the kernel un-compressed.
in function boot_get_kernel(): we should let the images->legacy_hdr_os point to the new copied image header, not the original image header in uImage which may be over-written in the kernel un-compressed process. This is a potential problem.
