octeontx2-pf: Check ntuple status from netdev feautre status

commit f2ac93bab0655466b8d9255f8b899a21370366e1 from
git@git.assembla.com:cavium/WindRiver.linux.git

Check ntuple status directly from netdev feature status rather than
reading the value from stored status. Since ntuple enable/disable will
not change the stored value.
