The CPU ID in KVM is supposed to be the APIC ID, so change the
KVM_CREATE_VCPU call to match it. The current behavior didn't break
anything yet because today the APIC ID is assumed to be equal to the CPU
index, but this won't be true in the future.

Changes v2:
- Change only i386 code (kvm_arch_vcpu_id())
Changes v3:
- Get CPUState as argument instead of CPUArchState
