Subject: dp83640: don't recieve time stamps twice

From: Dan Carpenter <[email protected]>

[ Upstream commit 9d386cd9a755c8293e8916264d4d053878a7c9c7 ]

This patch is prompted by a static checker warning about a potential use after free. The concern is that netif_rx_ni() can free "skb" and we call it twice.

When I look at the commit that added this, it looks like some stray lines were added accidentally. It doesn't make sense to me that we would recieve the same data two times. I asked the author but never recieved a response.

I can't test this code, but I'm pretty sure my patch is correct.
