staging: r8712u: Do not queue cloned skb
commit fa16e5ea25d7dd83f663f333e70713aa2fa5dffe upstream. Some post-3.4 kernels have a problem when a cloned skb is used in the RX path. This patch handles one such case for r8712u. The patch was suggested by Eric Dumazet. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
