ASoC: ops: Shift tested values in snd_soc_put_volsw() by +min

Fabien Parent requested to merge mediatek/aiot/team-baylibre/linux:fparent/merge-linux-5.10 into mtk-v5.10

commit 9bdd10d57a8807dba0003af0325191f3cec0f11c upstream.

While the val/val2 values passed in from userspace are always >= 0 integers, the limits of the control can be signed integers and the $min can be non-zero and less than zero. To correctly validate val/val2 against platform_max, add the $min offset to val first.
