batman-adv: Less checks in batadv_tvlv_unicast_send()

Browse source 
* 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.
