[B.A.T.M.A.N.] [PATCH] batman-adv: Don't free unicast skb on failure

The soft-interface transmission function expects that the unicast skb is still available when a send failed. Otherwise we would try to free the skb twice and create many different and hard to debug memory access failures due to access on not (anymore) allocated memory.
