output of volume-update command ERROR

[Trump.Zhang]

When running "nova volume-update" with correct arguments, the output will always be as follows:

ERROR (AttributeError): 'NoneType' object has no attribute '_info'

The reason is that the response body of corresponding NOVA API "os-volume_attachments" doesn't contains the "volumeAttachment" key.

    Remove _print_volume from volume-update

    Since the response of volume-update do not contain a body, just a status
    code 202, so when calling _print_volume(volume), there will be an error:
    `ERROR (AttributeError): 'NoneType' object has no attribute '_info'`.
