Subject: [PATCH 5.10 015/145] net: ethernet: mvneta: Fix error handling in mvneta_probe

From: Dinghao Liu <dinghao.liu@....edu.cn>

[ Upstream commit 58f60329a6be35a5653edb3fd2023ccef9eb9943 ]

When mvneta_port_power_up() fails, we should execute
cleanup functions after label err_netdev to avoid memleak.

Fixes: 41c2b6b4f0f80 ("net: ethernet: mvneta: Add back interface mode validation")
