NetApp ONTAP: Remove iSCSI/FC driver online volume extend support

Browse Source 
Cinder scheduler now checks backend capability online_extend_support
before performing an online volume extend operation. This patch makes
NetApp ONTAP iSCSI driver and FC driver report to the scheduler that
they don't support this feature, thus avoiding leaving a volume in
error_extending state after an online extending attempt.
