amd-xgbe: Fix DMA API debug warning
When running a kernel configured with CONFIG_DMA_API_DEBUG=y a warning
is issued:
DMA-API: device driver tries to sync DMA memory it has not allocated
This warning is the result of mapping the full range of the Rx buffer
pages allocated and then performing a dma_sync_single_for_cpu against
a calculated DMA address. The proper thing to do is to use the
dma_sync_single_range_for_cpu with a base DMA address and an offset.
