Subject: [PATCH 10/30] net: netrom: Add missing annotation for nr_node_start()

Precedence: bulk

Sparse reports a warning at nr_node_start()
warning: context imbalance in nr_node_start() - wrong count at exit
The root cause is the missing annotation at nr_node_start()
Add the missing __acquires(&nr_node_list_lock) annotation
