0fa5c23865 qemu: Taint cpu host-passthrough only after migration
From a discussion last year[1], Dan recommended libvirt drop the tain
flag for cpu host-passthrough, unless the VM has been migrated.

This repurposes the existing host-cpu taint flag to do just that.

Additional simplification is achieved by switching to skipping the loop
