net: libwx: fix Tx descriptor content for some tunnel packets

Browse source

The length of skb header was incorrectly calculated when transmit a tunnel
packet with outer IPv6 extension header, or a IP over IP packet which has
inner IPv6 header. Thus the correct Tx context descriptor cannot be
composed, resulting in Tx ring hang.
