batman-adv: fixed hash functions type to uint32_t instead of int
There are two reasons for this fix: - the result of choose_orig() and vis_choose() is an index and therefore it can't be negative. Hence it is correct to make the return type unsigned too. - sizeof(int) may not be the same on ALL the architectures. Since we plan to use choose_orig() as DHT hash function, we need to guarantee that, given the same argument, the result is the same. Then it is correct to explicitly express the size of the return type (and the second argument). Since the expected length is currently 4, uint32_t is the most convenient choice.
