Log:
wctdm24xxp: Reset the polarity debounce setting when battery is lost.

Wait until we have de-bounced the presence of battery before moving on the
check for changes in polarity. This removes the sometimes random
polarity messages generated on an FXO port when the far side drops
battery from a supervisor disconnect.
