dp83640: don't recieve time stamps twice

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.
