AdapterService: Only bind HeadsetService in ON state.

* there will be an endless loop to call doBind and cause many connectionRecords of HeadsetService while binding HeadsetService in BLE_ON state.
* allow to bind HeadsetService only when BT state is ON

Bug: 111730478
Test: Keep device in BLE_ON state -> kill com.android.phone process
      -> As time goes on, adb shell dumpsys activity services to check the connectionRecords of HeadsetService will not become more and more
