Please do not apply this patch as it is. Sashiko is right on both
points: the new -ENXIO path leaves the DMA buffer mapped, as the timeout
path does today, and a NACK of the last byte the DMA writes can be
missed. v2 fixes both. Patch 1/2 is not affected.

The block_data remark on patch 1/2 is a separate bug; I have sent a
patch for it on its own.
