net: mv643xx_eth: Drop the NETDEV_TX_BUSY return path

After adding proper stop/wake thresholds, we can expect a queue to never be full and drop the NETDEV_TX_BUSY return path. In any case, if the queue cannot accommodate a TSO packet, the packet would be discarded. Signed-off-by: Ezequiel Garcia <[email protected]> Signed-off-by: David S. Miller <[email protected]>
