John Hubbard 7846f58fba x86/boot: Fix boot regression caused by bootparam sanitizing ...

commit a90118c445 ("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: a90118c445 ("x86/boot: Save fields explicitly, zero out everything else")
