apic: kvm-apic: Fix crash due to access to freed memory region
kvm-apic.io_memory memory region had its parent set to NULL at
memory_region_init_io() time, so it ended up as a child in
/unattached contaner.
As result when kvm-apic instance was deleted, the child property
/unattached/kvm-apic-msi[XXX] contained a reference to
kvm-apic.io_memory address which was freed as part of kvm-apic.
Do the same as 'apic' and make kvm-apic instance the owner
of the memory region so that it won't end up in /unattached
and gets cleanly released along with related kvm-apic instance.
