Remove the reference of volume['instance_uuid']in VNX driver

Multiattach feature removed the column 'instance_uuid' and
'attached_host' from volume DB model. However, these 2 fields are
used by VNX driver to determine the volume's original status
in retype. This patch changed the VNX driver to not use those
removed fields.
