net: fec: use netif_tx_disable() rather than netif_stop_queue()

Browse source

We use netif_stop_queue() in several places where we want to ensure that
the start_xmit function is not running.  netif_stop_queue() is not
sufficient to achieve that - it merely sets a flag to indicate that the
transmit queue(s) should not be run.

netif_tx_disable() gives this guarantee, since it takes the transmit
queue lock while marking the queue stopped.  This will wait for the
transmit function to complete before returning.
