Every single call to qemuMigrationJobContinue needs to register a
cleanup callback in case the migrating domain dies between phases or
when migration is paused due to a failure in postcopy mode.
Let's integrate registering the callback in qemuMigrationJobContinue to
make sure the current thread does not release a migration job without
setting a cleanup callback.
