ACPI / scan: bail out early if failed to parse APIC ID for CPU

Enhance ACPI CPU hotplug driver to print clear error message and
bail out early if BIOS returns wrong value in ACPI MADT table or
_MAT method. Otherwise it will add the CPU device even if failed
to get APIC ID and fails any operations against sysfs interface:
/sys/devices/system/cpu/cpux/online
