NetApp ONTAP: Remove NFS driver online volume extending support

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