sit: fix regression: do not release skb->dst before xmit

The sit module makes use of skb->dst in it's xmit function, so since 93f154b ("net: release dst entry in dev_hard_start_xmit()") sit tunnels are broken, because the flag IFF_XMIT_DST_RELEASE is not unset. This patch unsets that flag for sit devices to fix this regression. Signed-off-by: Sascha Hlusiak <[email protected]> Acked-by: Eric Dumazet <[email protected]> Signed-off-by: David S.
