net: remove synchronize_net() from netdev_set_master()
In the old days, we used to access dev->master in __netif_receive_skb()
in a rcu_read_lock section.
So one synchronize_net() call was needed in netdev_set_master() to make
sure another cpu could not use old master while/after we release it.
We now use netdev_rx_handler infrastructure and added one
synchronize_net() call in bond_release()/bond_release_all()
Remove the obsolete synchronize_net() from netdev_set_master() and add
one in bridge del_nbp() after its netdev_rx_handler_unregister() call.
This makes enslave -d a bit faster.
