ASoC: qcom: Convert to generic PCM copy ops
This patch converts the qcom lpass 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.
