batman-adv: Less checks in batadv_tvlv_unicast_send()
* Let us return directly if a call of the batadv_orig_hash_find() function
returned a null pointer.
* Omit the initialisation for the variable "skb" at the beginning.
* Replace an assignment by a call of the kfree_skb() function
and delete the affected variable "ret" then.
