fpga: dfl: afu: Pass the correct device to dma_mapping_error()

[ Upstream commit 13069847a475b60069918dc9971f5adb42811ce3 ]

dma_mapping_error() was being called on a different device struct than
what was passed to map/unmap.  Besides rendering the error checking
ineffective, it caused a debug splat with CONFIG_DMA_API_DEBUG.
