ovpn: reset MAC header before passing skb up
After decapsulating a packet, the skb->mac_header still points to the
outer transport header.
Fix this by calling skb_reset_mac_header() in ovpn_netdev_write() to
ensure the MAC header points to the beginning of
the inner IP/network packet, as expected by the rest of the stack.
