    sched: fix freeing per-vcpu data in sched_move_domain()
    
    In case of an allocation error of per-vcpu data in sched_move_domain()
    the already allocated data is freed just using xfree(). This is wrong
    as some schedulers need to do additional operations (e.g. the arinc653
    scheduler needs to remove the vcpu-data from a list).
    
    So instead xfree() make use of the sched_free_vdata() hook.
