net: mvneta: fix DMA buffer unmapping in mvneta_rx()
This patch fixes a regression introduced by the commit a84e3289 ("net: mvneta: fix refilling for Rx DMA buffers"). Due to this commit the newly allocated Rx buffers are DMA-unmapped in place of those passed to the networking stack. Obviously, this causes data corruptions. This patch fixes the issue by ensuring that the right Rx buffers are DMA-unmapped.
