Revert "ASoC: wcd-mbhc: Fix plug removal detection from extension cable"

This reverts commit 099e839e ("ASoC:
wcd-mbhc: Fix plug removal detection from extension cable")'.
Headset insertion is giving spurious electrical insertion removal
interrupts. Hence headset is not detected properly. This is seen on
RCM devices for normal US headset on 8937/msmgold/msmtitanium. On MTP
some specific headsets are exhibiting this behavior.
