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

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.
