gro: reset skb_iif on reuse

Browse Source 
Like Herbert's change from a few days ago:

66c46d741e2e60f0e8b625b80edb0ab820c46d7a gro: Reset dev pointer on reuse

this may not be necessary at this point, but we should still clean up
the skb->skb_iif.  If not we may end up with an invalid valid for
skb->skb_iif when the skb is reused and the check is done in
__netif_receive_skb.
