[PATCH net] net: ethernet: mtk-star-emac: disable napi when connect and start PHY failed in mtk_star_enable()

[Zhengchao Shao]

When failed to connect to and start PHY in mtk_star_enable() for opening
device, napi isn't disabled. When open mtk star device next time, it will
reports a invalid opcode issue. Fix it. Only be compiled, not be tested.
