Subject: [PATCH -next] net: mediatek: remove set but not used variable 'status'

Fixes gcc '-Wunused-but-set-variable' warning:
drivers/net/ethernet/mediatek/mtk_eth_soc.c: In function mtk_handle_irq:
drivers/net/ethernet/mediatek/mtk_eth_soc.c:1951:6: warning: variable status set but not used [-Wunused-but-set-variable]

It is not used since commit 296c9120752b ("net: ethernet: mediatek: Add MT7628/88 SoC support")
