Subject: [PATCH 4/6] net: ravb: Start TX queues after HW initialization succeeded

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

ravb_phy_start() may fail. If that happens, the TX queues will remain
started. Thus, move the netif_tx_start_all_queues() after PHY is
successfully initialized.

Fixes: c156633f1353 ("Renesas Ethernet AVB driver proper")
