Antonio Quartulli 944734c3d3 batman-adv: fix potential kernel paging error for unicast transmissions 
[ Upstream commit 70b271a78b ]

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.
