Don't call the node iteration function inside the node table / node
iterate lock.
This causes LORs and deadlocks as some code paths will have the com lock
held when calling ieee80211_iterate_nodes().
Here, the comlock isn't held during the node table and node iteration
locks; and the callback isn't called with any (extra) lock held.
