Bluetooth: Fix for BT grey out when cleanup called before enable

Fix for BT grey out when cleanup is called before enable due to
START_TIMEOUT. In this scenario BT cleanup is not handled properly
and hal callback is not reset. Successive BT enable fails with
adapter service not able to set the jni call back.
