    Keep instance state if ssh failed during migration

    When block-migrating a vm between two compute nodes,
    if the destination node lacks ssh daemon or refuses
    ssh connection, the block-migration would fail and
    cause damage to the vm, vm will be in error state
    for a certain time.

    Actually, the VM itself is not changed, the resize
    action failed at preparation stage, so don't need to
    set it to 'ERROR' state.
