    Use correct arguments in task inits

    The CreateAndConnectCfgDrive and DeleteVOpt tasks were passing the
    instance into the task.Task init as the first argument. The first arg
    for the Task init is actually the task name [1]. This means that those
    task names were string representations of the instance which will cause
    failures if there are any non-ascii characters. This corrects the Task
    init calls by removing instance as the first argument. The name kwarg
    is now being used throughout the PowerVM tasks to avoid similar issues
    in the future.
