ASoC: ops: Fix the bounds checking in snd_soc_put_volsw_sx and snd_soc_put_xr_sx

The $val in both functions has a range between 0 and an arbitrary limit
whereas the range specified with the $min and $max can start
from a negative number. To do the out of bound check correctly, the
$val must be added the $min offset.
