Setting ib1 state to MTK_FOE_STATE_UNBIND in __mtk_foe_entry_clear
routine as done by commit 0e80707d94e4c8 ("net: ethernet: mtk_eth_soc:
fix typo in __mtk_foe_entry_clear") breaks flow offloading, at least
on older MTK_NETSYS_V1 SoCs, OpenWrt users have confirmed the bug on
MT7622 and MT7621 systems.
Felix Fietkau suggested to use MTK_FOE_STATE_INVALID instead which
works well on both, MTK_NETSYS_V1 and MTK_NETSYS_V2.
Tested on MT7622 (Linksys E8450) and MT7986 (BananaPi BPI-R3).
