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.
