      batman-adv: Even Batman should not dereference NULL pointers · ed7809d9

      There's a problem in net/batman-adv/unicast.c::frag_send_skb().
      dev_alloc_skb() allocates memory and may fail, thus returning NULL. If
      this happens we'll pass a NULL pointer on to skb_split() which in turn
      hands it to skb_split_inside_header() from where it gets passed to
      skb_put() that lets skb_tail_pointer() play with it and that function
      dereferences it. And thus the bat dies.
      
      While I was at it I also moved the call to dev_alloc_skb() above the
      assignment to 'unicast_packet' since there's no reason to do that
      assignment if the memory allocation fails.
