Arthur Nascimento Santos 510613e135 NetApp ONTAP: Fix extend volume for iSCSI/FCP

Due to a characteristic on ONTAP devices, the volume extend
operation has a max resize size limited by underlying LUN's
geometry, so the support for extend online volumes was
disabled.

This patch fixes it by allowing a volume (attached or not)
to be extended up to 16TB, which is the max LUN size
supported by ONTAP.

NFS online_extend_support is still disabled due to a bug [0]
found on the generic implementation for NFS driver, which
ONTAP NFS driver relies on.
