[ Upstream commit 32d57f667f871bc5a8babbe27ea4c5e668ee0ea8 ]
Condition, which checks whether the netdev has hashing enabled is
inverted. Basically, the tagged commit effectively disabled passing flow
hash from descriptor to skb, unless user *disables* it via Ethtool.
Commit a876c3ba59a6 ("i40e/i40evf: properly report Rx packet hash")
fixed this problem, but only for i40e.
Invert the condition now in iavf and unblock passing hash to skbs again.
Fixes: 857942fd1aa1 ("i40e: Fix Rx hash reported to the stack by our driver")
