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.
Fixes: bc6107771bb4 ("eth: fbnic: Allocate a netdevice and napi vectors with queues")
