ASoC: WM8990: Fix kcontrol's private value use in put callback
Function wm899x_outpga_put_volsw_vu misuses the kcontrol's private value by still accessing it as bitfields even SOC_SINGLE_VALUE constructs it as a pointer into struct soc_mixer_control after the commit 4eaa9819dc08d7bfd1065ce530e31b18a119dcaf. This is very similar fix than fix to TLV320AIC3X codec made by Eero Nurkkala <ext-eero.nurkkala@nokia.com>. This fix is compile tested only.
