x86/cpu/topology: Reject unknown APIC IDs on ACPI hotplug

Browse source

The topology bitmaps track all possible APIC IDs which have been registered
during enumeration. As sizing and further topology information is going to
be derived from these bitmaps, reject attempts to hotplug an APIC ID which
was not registered during enumeration.
