Title:
  nova volume-update is throwing an ERROR

Status in Python client library for Nova:
  Fix Released

Bug description:
  I am Trying to use nova volume-update, but it is throwing an error as
  below

  nova volume-update 46e36131-8654-4cb3-a8ed-b39b2660aa2f 14db127c-5c66-42cf-b309-b90c1e4b5fe9 7414d297-c6c7-4357-a4a0-918066c4f6b7
  ERROR: 'NoneType' object has no attribute '_info'

  Below are the steps followed

  Created as a VM
      nova boot --image 74b7b094-78e4-4070-8b43-9f902ac80268 --flavor 1 newH

  Attached a Volume to the created VM
      nova volume-attach 46e36131-8654-4cb3-a8ed-b39b2660aa2f 14db127c-5c66-42cf-b309-b90c1e4b5fe9 /dev/vdc

  Created a new volume
      cinder create 1 --display_name debug

  Now I am trying to update the volume attachment with new volume
      nova volume-update 46e36131-8654-4cb3-a8ed-b39b2660aa2f 14db127c-5c66-42cf-b309-b90c1e4b5fe9 7414d297-c6c7-4357-a4a0-918066c4f6b7

  After the executing the above command

  The volume which is in-use, is reaching to detaching state.


  Here is the detailed log

  $ nova --debug volume-update 46e36131-8654-4cb3-a8ed-b39b2660aa2f
