batman-adv: annotate functions which may reallocate the skbuff

Browse source

When a function is called which reallocated the skbuff, it is necessary to
reacquire the pointers into the skb data. Otherwise they might cause an
use-after-free.

But is hard to identify such case when it is not clear that helpers are
actually using skb-reallocating functions.
