net: ethernet: mtk_eth_soc: Reuse value using READ_ONCE instead of re-rereading it

Browse source

In mtk_flow_entry_update_l2, the hwe->ib1 is read using READ_ONCE at the
beginning of the function, checked, and then re-read from hwe->ib1,
may void all guarantees of the checks. Reuse the value that was read by
READ_ONCE to ensure the consistency of the ib1 throughout the function.
