    NetApp ONTAP: Fix reporting of provisioned_capacity_gb

    The ONTAP drivers in Cinder ("7mode" and "cmode") cannot
    reliably and efficiently track provisioned_capacity_gb as expected
    by the Cinder scheduler.

    The driver authors originally assumed that provisioned_capacity_gb
    is consumed space on the backend. This results in miscalculation of
    over subscription in the Cinder scheduler.

    The fix adopted here is to remove this wrong reporting and rely on
    calculation of the provisioned_capacity_gb in the scheduler.
