Fix v3 volume list based on image_metadata

volume list filtered on image_metadata does not work as expected.
The filtering based on image_metadata depended on non existent
utility for extracting image_metadata.
Fixed the issue by calling appropriate utility module
for extracting image_metadata. Looks like a typo.
