When setting pause modes, we check that pause->rx_pause == pause->tx_pause, but only when pause autoneg is enabled. When pause autoneg is disabled, we still allow pause->rx_pause != pause->tx_pause, which is incorrect when the MAC does not support asymetric pause, and causes mvneta to issue a warning. Fix this by removing the test for pause->autoneg, so we always check that pause->rx_pause == pause->tx_pause for network devices that do not support AsymPause.
