    Fix volume creation from image with allowed_direct_url_schemes

    When CONF.allowed_direct_url_schemes is set to ['file'] and
    Glance image has direct_url or locations metadata with 'file:///'
    scheme, cinder tries to directly read the image data from the
    local file. However, currently the code is broken because return
    value from get_location() has been changed to a tuple.
    This fixes the code so that it can handle the metadata correctly.
