Igor Mammedov f6e984443f apic: Use apic_id as apic's migration instance_id
instance_id is generated by last_used_id + 1 for a given device type
so for QEMU with 3 CPUs instance_id for APICs is a seti of [0, 1, 2]
When CPU in the middle is hot-removed and migration started
APICs with instance_ids 0 and 2 are transferred in migration stream.
However target starts with 2 CPUs and APICs' instance_ids are
generated from scratch [0, 1] hence migration fails with error
  Unknown savevm section or instance 'apic' 2

Fix issue by manually registering APIC's vmsd with apic_id as
instance_id, in this case instance_id on target will always
match instance_id on source as apic_id is the same for a given
cpu instance.
