Audio: Do not disconnect profiles till Bluetooth Off

- Disconnecting and clearing Bluetooth Profiles during
  Turning Off State doesn't give chance to A2DP/AVRCP
  profiles to save and retain Audio related data like
  Volume level.
- This change ensures Audio Service only disconnect
  Bluetooth Profile on receiving Bluetooth Off state.
