ALSA: hdsp: Convert to generic PCM copy ops

Browse source

This patch converts the hdsp driver code to use the new unified PCM
copy callback.  It's a straightforward conversion from *_user() to
*_iter() variants.

Note that copy_from/to_iter() returns the copied bytes, hence the
error condition is adjusted accordingly.
