Set the Bluetooth state to OFF if there is disable timeout error

Previously, if there was "disable timeout" error during Bluetooth
shutdown, the Bluetooth state was set back to ON. However, the
internal Bluetooth stack runtime state was cleaned-up and
practically unusable.

The solution is not to re-enable Bluetooth if there is a
"disable timeout" error.
