qemu: Transfer migration statistics to destination
qemu: Transfer migration statistics to destination

When migrating a transient domain or with VIR_MIGRATE_UNDEFINE_SOURCE
flag, the domain may disappear from source host. And so will migration
statistics associated with the domain. We need to transfer the
statistics at the end of a migration so that they can be queried at the
destination host.
