[PATCH v2] net: korina: fix return value

[Vincent Stehlé]

The ndo_start_xmit() method must not attempt to free the skb to transmit
when returning NETDEV_TX_BUSY. Therefore, make sure the
korina_send_packet() function returns NETDEV_TX_OK when it frees a packet.

Fixes: ef11291bcd5f ("Add support the Korina (IDT RC32434) Ethernet MAC")

- Keep freeing the packet but return NETDEV_TX_OK, as suggested by Jakub
