ASoC: Fix mask/val_mask confusion snd_soc_dapm_put_volsw()

Browse source 
snd_soc_dapm_put_volsw() has variables for both the unshifted and
shifted mask for updates commit 97404f (ASoC: Do DAPM control updates in
the middle of DAPM sequences) got confused between the two of these.
Since there's no need to keep a copy of the unshifted mask fix this and
simplify the code by using only one mask variable.

[Completely rewrote the changelog to describe the issue -- broonie.]
