eth: fbnic: Use wake instead of start
fbnic_up() calls netif_tx_start_all_queues(), which only clears __QUEUE_STATE_DRV_XOFF. If qdisc backlog has accumulated on any TX queue before the reconfiguration (e.g. ring resize via ethtool -G), start does not call __netif_schedule() to kick the qdisc, so the pending backlog is never drained and the queue stalls. Switch to netif_tx_wake_all_queues(), which clears DRV_XOFF and also calls __netif_schedule() on every queue, ensuring any backlog that built up before the down/up cycle is promptly dequeued.
