    Fix incorrect volume type value in ng images create volume form

    The value of the 'volume_type' is determined by the 'volumeType'
    object [1]. The value of the 'volume_type' changes only the
    'volumeType' object changes. However, the current value of the
    'volume_type' is changed according to the volume object change [2].

    It will cause a phenomenon, when the page is initialized, the value
    of 'volume_type' is empty, when we switch volume types drop-down box,
    its value is also empty, only change the name, description, size and
    availability zone, the value of 'volume_type' is the page selection.
