    Fix _attachment_reserve to not allow attaching an invalid status volume
    
    It is currently possible to create a volume attachment for a server
    when the volume is in error status because of the override logic
    in the _attachment_reserve method. What results is that the volume
    attach operation fails in nova-compute which rolls back and deletes
    the volume attachment, which puts the volume into 'available' status
    because it no longer has any attachments, which in fact it should
    have never allowed the attachment create/reserve in the first place.
    
    This updates the override logic such that a volume without any
    attachments which is in an invalid status will result in an error
    being raised.

Title:
  Volume status changed from error to available

Status in Cinder:
  Fix Released
Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Description
  ===========
  After creating a volume which resulted with status = "error", an attempt to attach the volume to VM will fail and will change the volume status to - "available".

  Steps to reproduce
  ==================
  1. Create volume with status = "error".
  2. Try to attach the volume to the VM.
  3. Check the volume status.

  Expected result
  ===============
  1. Volume will be created with status = "error".
  2. Attachment to VM will failed.
  3. Volume status will be - "error"

  Actual result
  =============
  1. Volume created in status = "error".
  2. Attachment attempt to VM will fail.
  3. Volume status changed from "error" to "available".
