ASoC: msm8x16-wcd: add more strict conditions for extension cable
The current conditions in plug report function for extension cable
insertion are not enough. It will also let in some other scenario,
e.g., the plug type correction from headphone to headset.
Add more strict conditions to just let in electrical insertion
of extension cable and electrical removal detection.
