commit a90118c445cc ("x86/boot: Save fields explicitly, zero out
everything else") had two errors:
* It preserved boot_params.acpi_rsdp_addr, and
* It failed to preserve boot_params.hdr
Therefore, zero out acpi_rsdp_addr, and preserve hdr.
Fixes: a90118c445cc ("x86/boot: Save fields explicitly, zero out everything
else")
