[TG3]: Fix possible NULL deref in tg3_run_loopback().
tg3_run_loopback doesn't check that dev_alloc_skb() returns anything useful. Even if dev_alloc_skb() fails to return an skb to us we'll happily go on and assume it did, so we risk dereferencing a NULL pointer. Much better to fail gracefully by returning -ENOMEM than crashing here. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
