mmc: omap_hsmmc: DMA unmap only once in case of MMC error
Reported by Russell King:
mmcblk0: error -84 transferring data, sector 149201, nr 64,
cmd response 0x900, card status 0xb00
mmcblk0: retrying using single block read
WARNING: at lib/dma-debug.c:811 check_unmap
omap_hsmmc omap_hsmmc.0: DMA-API: device driver tries to free DMA memory
it has not allocated [device address=0x0000000080933000] [size=20480 bytes]
In case of an error dma_unmap() is issued in omap_hsmmc_dma_cleanup()
and then again in omap_hsmmc_post_req(). Resolve this by clearing the
host_cookie to indicate there is no DMA mapped memory to unmap.
