net: ethernet: mtk-star-emac: fix error path in RX handling
The dma_addr field in desc_data must not be overwritten until after the new skb is mapped. Currently we do replace it with uninitialized value in error path. This change fixes it by moving the assignment before the label to which we jump after mapping or allocation errors.
