Revert (mostly) a patch from the vCPU RESET cleanup that open coded some
APIC shenanigans to avoid stuffing vcpu->arch.apic_base at vCPU creation,
and completely overlooked the side effects on apic_hw_disabled. I went
for a revert as I think the original behavior is the least awful solution,
just somewhat poorly documented.
The second patch adds WARNs to detect "overflow", where "overflow" means
KVM incorrectly increments apic_hw_disabled.
