ASoC: wcd9330: Notify MBHC as soon as HPH PA is turned off

Sometimes it is observed that MBHC driver re-enables
PA even though HPH PA event triggered by DAPM turns
off the PAs. This would cause over current circuit
to trigger and audio get muted. To avoid this notify
MBHC immediately after the PAs are turned off without
waiting for the Click and Pop time of 5milli-seconds.
