ASoC: qcom: Fix error code in lpass_platform_copy()

Browse source

The copy_to/from_user() functions return the number of bytes remaining
to be copied.  This function needs to return negative error codes
because snd_soc_pcm_component_copy_user() treats positive returns as
success in soc_component_ret().
