libxl: migration: defer removing VM until finish phase
    
    If for any reason the restore of a VM fails on the destination host
    in a migration operation, the VM is removed (if not persistent) from
    the virDomainObjList, meaning it is no longer available for additional
    cleanup or processing in the finish phase. Defer removing the VM from
    the virDomainObjList until the finish phase, which already contains
    logic to remove the VM.
