Preload timeout and retry mechanism (2/3)
If the Preload process was stuck due to unknown hardware init failure,
a 8-second ENABLE_TIMEOUT timeout would be eventually expired in Java layer
at AdapterState and attempted to set BT state back to STATE_OFF.
However BluetoothManagerService did not handle this case accordingly and led
to state mis-matching between Java layer and BTIF at the end.
Add the processing logic in AdapterState to handle the case when an explicit
STATE_OFF notification from BTIF was received in the TurningOn Pending state.
