[PATCH net-next] net: ethernet: mediatek: enhance with avoiding superfluous assignment inside mtk_get_ethtool_stats

[sean.wang]

From: Sean Wang <sean.w...@mediatek.com>

data_src is unchanged inside the loop, so this patch moves
the assignment to outside the loop to avoid unnecessarily
assignment
