Update _resize_volume_file() to support appropriate permissions

ibmnas driver inherits _set_rw_permissions_for_all() from nfs.py
which sets 666 to the volumes. Changes are expected to be made in
nfs.py such that it sets 600 or 660 permissions, by doing so
ibmnas driver fails performing the operation _resize_volume_file()

Adding run_as_root in resize_volume operation.
