Fix InstanceLocalityFilter scheduler filter

Commit I51254e20151fe1d6771897e64a8d0bdf2d674d03 introduces new error:
We use novaclient extensions instead of Nova API extensions. In such
case, InstanceLocalityFilter won't find Nova ExtendedServerAttributes
extension and will raise CinderException.

This patch fixes novaclient usage in a right way.
