ASoC: dapm: Make sure register value is in sync with DAPM kcontrol state
Commit c9e065c27fe9 ("ASoC: dapm: Make sure to always update the DAPM graph in _put_volsw()") stopped updating register values in those cases where initial after boot state of kcontrol appears to not change but where register value still needs update because it is not in sync with the kcontrol state. Fix this by doing snd_soc_test_bits() unconditionally as it was before but by using separate flags for kcontrol and register state changes. This allow both DAPM graph to be updated when disabling auto-muted control and update register if it is out-of-sync in respect of kcontrol state.
