Andy Shevchenko afde3be121 dmatest: check for dma mapping error 
The kernel emits a warning if CONFIG_DMA_API_DEBUG=y:

  WARNING: at lib/dma-debug.c:933 check_unmap+0x5d6/0x6ac()
  dw_dmac dw_dmac.0: DMA-API: device driver failed to check map error[device address=0x0000000035698305] [size=14365 bytes] [mapped as single]

Fix this by adding the required checking of the dma_map_single() return
value.
