bareudp: Convert bareudp_exit_batch_rtnl() to ->exit_rtnl().

Browse Source 
bareudp_exit_batch_rtnl() iterates the dying netns list and performs the
same operation for each.

Let's use ->exit_rtnl().

While at it, we replace unregister_netdevice_queue() with
bareudp_dellink() for better cleanup.  It unlinks the device
from net_generic(net, bareudp_net_id)->bareudp_list, but there
is no real issue as both the dev and the list are freed later.
