Re: [PATCH net-next v2] net: Updates to netif_index_is_vrf

As Eric noted netif_index_is_vrf is not called with rcu_read_lock held,
so wrap the dev_get_by_index_rcu in rcu_read_lock and unlock.

If VRF is not enabled or oif is 0 skip the device lookup. In both cases
index cannot be the VRF master.

v2:
- per Florian's suggestion keep the dev_get_by_index_rcu and wrap with
  rcu_read_lock/unlock versus moving to dev_get_by_index with dev_hold/put

Applied, thanks.
