[B.A.T.M.A.N.] [PATCH] batman-adv: Remove variable deprecated by skb_put_data

[Sven Eckelmann <sven@narfation.org>]

skb_put_data makes it unnecessary to store the skb_put return value to copy
some data to the packet. The returned pointer of skb_put_data should
therefore not stored by functions which previously only used it to copy
some data.

This patch belongs to the series
 https://patchwork.open-mesh.org/project/b.a.t.m.a.n./list/?series=11
It must not be squashed in the "batman-adv: introduce and use skb_put_data()"
because it is already part of net-next and we must port the change in our
patch in a separate pull request.
