ovs: Remove rtnl_lock() from ovs_exit_net()
Here we iterate for_each_net() and removes vport from alive net to the exiting net. ovs_net::dps are protected by ovs_mutex(), and the others, who change it (ovs_dp_cmd_new(), __dp_destroy()) also take it. The same with datapath::ports list. So, we remove rtnl_lock() here. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
