x86/cpu/topology: Remove limit of CPUs due to disabled IO/APIC
commit 73da582a476ea6e3512f89f8ed57dfed945829a2 upstream.
The rework of possible CPUs management erroneously disabled SMP when the
IO/APIC is disabled either by the 'noapic' command line parameter or during
IO/APIC setup. SMP is possible without IO/APIC.
Remove the ioapic_is_disabled conditions from the relevant possible CPU
management code paths to restore the orgininal behaviour.
