bonding: use exit_batch_rtnl() method

Browse source

exit_batch_rtnl() is called while RTNL is held,
and devices to be unregistered can be queued in the dev_kill_list.

This saves one rtnl_lock()/rtnl_unlock() pair,
and one unregister_netdevice_many() call.

v2: Added bond_net_pre_exit() method to make sure bond_destroy_sysfs()
    is called before we unregister the devices in bond_net_exit_batch_rtnl
