[0/3] dma-mapping: Trace more error paths

Message

Some DMA functions are not traced when they fail. I found this pretty
confusing, since it seems like the device skips calling the DMA function
and fails anyway. This series adds some additional tracepoints to
address this.

  dma-mapping: Trace dma_alloc/free direction
  dma-mapping: Use trace_dma_alloc for dma_alloc* instead of using
    trace_dma_map
  dma-mapping: Trace more error paths
