Juergen Gross 182ddd1619 x86/boot: Clear RSDP address in boot_params for broken loaders ...

Gunnar Krueger reported a systemd-boot failure and bisected it down to:

  e6e094e053 ("x86/acpi, x86/boot: Take RSDP address from boot params if available")

In case a broken boot loader doesn't clear its 'struct boot_params', clear
rsdp_addr in sanitize_boot_params().
