Subject: [PATCH] cxgb4: fix crash due to manipulating queues before
registration
Before commit "net: allocate tx queues in register_netdevice"
netif_tx_stop_all_queues and related functions could be used between
device allocation and registration but now only after registration.
cxgb4 has such a call before registration and crashes now. Move it
after register_netdev.
