net: sonic: return NETDEV_TX_OK if failed to map buffer
[ Upstream commit 6e1cdedcf0362fed3aedfe051d46bd7ee2a85fe1 ]
NETDEV_TX_BUSY really should only be used by drivers that call
netif_tx_stop_queue() at the wrong moment. If dma_map_single() is
failed to map tx DMA buffer, it might trigger an infinite loop.
This patch use NETDEV_TX_OK instead of NETDEV_TX_BUSY, and change
printk to pr_err_ratelimited.
