Title:
  Can't Update Volume Status on dashboard if cinder volume stunk at
  reserved status

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  I am using Openstack Version Queens with CentOS7
   OpenStack Horizon version: 
  # rpm -qa | grep horizon
  puppet-horizon-12.4.0-1.el7.noarch
  python-django-horizon-13.0.0-1.el7.noarch

  
  several of my volumes stunk at reserved status for some reason. I tried to click "Update Volume Status" button on GUI, but no window pop out. Instead, a ERROR message display on the up-right corner.

  "Danger: An error occurred. Please try again later."

  The horizon.log complains:

  I can successfully reset-state with openstack CLI command.

  cinder reset-state --state available <volume id>
