PATCH mv643xx_eth: Unmap DMA buffers in receive path

["Dale Farnsworth" <dale@farnsworth.org>]

From: Dale Farnsworth <dale@farnsworth.org>

Fix a missing call to dma_unmap_single() in the receive path.  Without
this call, errors have been observed on non-cache-coherent systems.

Sorry.  Patch was against an old version.
This one's current.
