ixgbe: Fix usage of netif_*_all_queues() with netif_carrier_{off|on}()

Browse Source 
netif_carrier_off() is sufficient to stop Tx into the driver.  Stopping the Tx
queues is redundant and unnecessary.  By the same token, netif_carrier_on()
will be sufficient to re-enable Tx, so waking the queues is unnecessary.
