[B.A.T.M.A.N.] [PATCH 2/3] batctl: Free hash iterator when breaking out of loop

[Sven Eckelmann <sven@narfation.org>]

The hash iterator is automatically allocated and freed by the hash_iterate
function. But when using break (or goto outside of loop) during the iteration
loop, the caller has to handle the free-operation of the hash_iterator to avoid
memory leaks.
