net: ethernet: mtk_eth_soc: fix potential memory leak in mtk_rx_alloc()
When fail to dma_map_single() in mtk_rx_alloc(), it returns directly.
But the memory allocated for local variable data is not freed, and
local variabel data has not been attached to ring->data[i] yet, so the
memory allocated for local variable data will not be freed outside
mtk_rx_alloc() too. Thus memory leak would occur in this scenario.
Add skb_free_frag(data) when dma_map_single() failed.
