Subject: [PATCH net v3 1/2] net: ethernet: mtk_eth_soc: fix resource leak in error path

In mtk_probe(), when mtk_ppe_init() or mtk_eth_offload_init() failed,
mtk_mdio_cleanup() isn't called. Fix it.

Fixes: ba37b7caf1ed ("net: ethernet: mtk_eth_soc: add support for initializing the PPE")
Fixes: 502e84e2382d ("net: ethernet: mtk_eth_soc: add flow offloading support")
