Subject: bonding: get netdev_rx_handler_unregister out of locks
From: Veaceslav Falico <vfalico@xxxxxxxxxx>
[ Upstream commit fcd99434fb5c137274d2e15dd2a6a7455f0f29ff ]
Now that netdev_rx_handler_unregister contains synchronize_net(), we need
to call it outside of bond->lock, cause it might sleep. Also, remove the
already unneded synchronize_net().
