x86, boot: Not need to check setup_header version for setup_data

Browse source

That is for bootloaders.

setup_data is in setup_header, and bootloader is copying that from bzImage.
So for old bootloader should keep that as 0 already.

old kexec-tools till now for elf image set setup_data to 0, so it is ok.
