staging: wlags49_h2: Fix use of skb after netif_rx
This patch moves a call to netif_rx(skb) after a subsequent reference to
skb, because netif_rx may call kfree_skb via enqueue_to_backlog on its
argument.
This was found using the following semantic match.
// <smpl>
@@
expression skb, e,e1;
@@
(
netif_rx(skb);
|
netif_rx_ni(skb);
)
... when != skb = e
(
skb = e1
|
* skb
)
// </smpl>
