[S390]: Fix use of skb after netif_rx
Recently, Wang Chen submitted a patch
(d30f53aeb31d453a5230f526bea592af07944564) to move a call to netif_rx(skb)
after a subsequent reference to skb, because netif_rx may call kfree_skb on
its argument. netif_rx_ni calls netif_rx, so the same problem occurs in
the files below.
I have left the updating of dev->last_rx after the calls to netif_rx_ni
because it seems time dependent, but moved the other field updates before.
This was found using the following semantic match.
(http://www.emn.fr/x-info/coccinelle/)

expression skb, e,e1;

(
netif_rx(skb);

netif_rx_ni(skb);

... when != skb = e
(
skb = e1
|
* skb
)
