net: ethernet: mtk_eth_soc: fix error checking in mtk_mac_config()
commit 214b3369ab9b0a6f28d6c970220c209417edbc65 upstream.
Clang static analysis reports this problem
mtk_eth_soc.c:394:7: warning: Branch condition evaluates
to a garbage value
if (err)
^~~
err is not initialized and only conditionally set.
So intitialize err.
