sky2: Lock transmit queue while disabling device
netif_device_detach() does not take the tx_lock, so it's possible that
a call to sky2_xmit_frame is still in progress after
netif_device_detach() is complete.
Take netif_tx_lock() to make sure all transmits have stopped while
we're disabling the devices and that no other CPU is still
transmitting a frame after we've disabling the device.
Proposed fix for "sky2 panic under load" reported by Berck E. Nash.
