net: ethernet: mtk_eth_soc: fix off by one check of ARRAY_SIZE

In mtk_wed_tx_ring_setup(.., int idx, ..), idx is used as an index here
  struct mtk_wed_ring *ring = &dev->tx_ring[idx];

The bounds of idx are checked here
  BUG_ON(idx > ARRAY_SIZE(dev->tx_ring));

If idx is the size of the array, it will pass this check and overflow.
So change the check to >= .
