net: ethernet: mtk_wed: setup WDMA_RING_TX(0) for non-DBDC MT7986
WDMA_RING_TX(0) is required to set MTK_WED_WDMA_RING_TX for WED RX
but on a non-DBDC MT7986 it is never setup because idx is 1.
Setting MTK_WED_WDMA_RING_TX with WDMA_RING_TX(1) is not feasible because
WED still tries to send through WDMA_RING_TX(0). This is verified with
register dump.
Fix this by calling mtk_wed_wdma_tx_ring_setup if wed is v2 and
rx_ring[0] is not allocated and reset tx_wdma[0] if it's already
allocated also add error messages and bail when mtk_wed_start fails.
Fixes: 4c5de09eb0d0 ("net: ethernet: mtk_wed: add configure wed wo support")
