hardware/qcom: 8660: Fix to mute issue from second voip call

- Make a voip call, mute the mic and end the call.
Now make another voip call, observe mic mute still
present.
- the mute flag related to voip session is not reset
when the call ended. It will result in carry forwarding
the mute to next new voip session and remains muted
until the mic Mute button is pressed again.
- Reset the mute flag of voip and voice session
at the end of respective call sessions.
