commit 40cf447d28a5c9842f3546c4e7fe4efa682293cf

    Avoid lazy-loading instance.id when cross_az_attach=False
    
    The instance is no longer created in the API so the id attribute
    won't be set, which means when checking the instance AZ against
    the volume AZ, if they don't match we can't put the instance.id
    in the error message. We shouldn't have been putting the instance
    primary key in the error message anyway.
    
    This fixes the bug by using the instance.uuid which is set in
    this object in _provision_instances.

  The instance isn't created in the API since Ocata so there is no
  instance.id field.
