Staging: batman-adv: initialize static hash iterators
instead of dynamically registering hash iterators, calling functions are
changed to register the iterator objects statically. The two advantages are:
* no memory leaks when aborting from hash_iterate()
* no calls to kmalloc/kfree, therefore a little faster/safer
Tested with 9 QEMU instances, no obvious regression found.
