ASoC: dapm: Fix auto-disable for inverted controls
We need to make sure that the control's cached value is initialized to the
same
value as the control's widget->on_val. Otherwise updates might be lost.
Reproduce step:
---------------------
1. system boot up
2. dmesg | grep -i "call trace"
Call Trace:
