Resolve some memory leaks due to incorrect for loop / ao2 ref usage.

A common idiom in Asterisk is to due something like:

for (ao2_obj = list_beginning; ao2_obj = next_item; ao2_ref(ao2_obj, -1)) {
    ...do stuff...
}

This is nice because it automatically takes care of the object references
for you. However, there is a pitfall here. If a break statement is in the
for loop, then the current reference is not cleaned up. In some cases, this
is on purpose, but in others there is a leak. This commit fixes the leak
cases.
