batman-adv: fix potential kernel paging error for unicast transmissions batadv_send_skb_prepare_unicast(_4addr) might reallocate the skb's data. If it does then our ethhdr pointer is not valid anymore in batadv_send_skb_unicast(), resulting in a kernel paging error. Fixing this by refetching the ethhdr pointer after the potential reallocation. Signed-off-by: Linus Lüssing <linus.luessing@web.de> Signed-off-by: Antonio Quartulli <antonio@meshcoding.com>
