sh_eth: advance 'rxdesc' later in sh_eth_ring_format()
Iff dma_map_single() fails, 'rxdesc' should point to the last filled RX
descriptor, so that it can be marked as the last one, however the driver
would have already advanced it by that time. In order to fix that, only
fill an RX descriptor once all the data for it is ready.
