dma: dw: Align error code for xrun reporting

Browse source 
The hda driver uses -EPIPE to signal xrun, as proposed in the alsa lib
https://www.alsa-project.org/alsa-doc/alsa-lib/pcm.html. This commit
changes the xrun error code in dw dma driver from -ENODATA to -EPIPE to
make it consistent across drivers.
