x86/ACPI: keep x86_cpu_to_acpiid mapping valid on CPU hotplug
We may or may not have all possible CPUs in MADT on boot but in any
case we're overwriting x86_cpu_to_acpiid mapping with U32_MAX when
acpi_register_lapic() is called again on the CPU hotplug path:
acpi_processor_hotadd_init()
-> acpi_map_cpu()
-> acpi_register_lapic()
As we have the required acpi_id information in acpi_processor_hotadd_init()
propagate it to acpi_map_cpu() to always keep x86_cpu_to_acpiid
mapping valid.
