[next-queue PATCH v4 1/8] igb: Fix not adding filter elements to the list

[Vinicius Costa Gomes]

Because the order of the parameters passes to 'hlist_add_behind()' was
inverted, the 'parent' node was added "behind" the 'input', as input
is not in the list, this causes the 'input' node to be lost.

Fixes: 0e71def25281 ("igb: add support of RX network flow classification")
