netdev: Kill NETIF_F_MULTI_QUEUE.

There is no need for a feature bit for something that
can be tested by simply checking the TX queue count.

device is still operational. netdev->queue_lock is still used when the device
comes online or when it's completely shut down (unregister_netdev(), etc.).
Finally, the base driver should indicate that it is a multiqueue device. The
feature flag NETIF_F_MULTI_QUEUE should be added to the netdev->features
bitmap on device initialization. Below is an example from e1000:
#ifdef CONFIG_E1000_MQ
if ( (adapter->hw.mac.type == e1000_82571) ||
(adapter->hw.mac.type == e1000_82572) ||
(adapter->hw.mac.type == e1000_80003es2lan))
netdev->features |= NETIF_F_MULTI_QUEUE;
#endif
