[PATCH 2/8] ASoC: ops: Fix return value in snd_soc_limit_volume()

["Amadeusz Sławiński" <amade@asmblr.net>]

As documented snd_soc_limit_volume() should return 0 on success, however
at some point in time this promise was broken when
snd_soc_clip_to_platform_max() was refactored, refactor it once again
using __free() to automatically free struct snd_ctl_elem_value and
return proper value.

Fixes: 7e10d7242ea8 ("ASoC: ops: dynamically allocate struct snd_ctl_elem_value")
