BT: Set persiste Bluetooth State during enable timeout case

Use case: When enable timeout occurs during S&S testing and
Bluetooth state is moved from Turning On to Off.

Steps: Changes related to enable timeout case, to test the
changes, S&S testing can be done.

Failure: Changes done to handle Bluetooth enable timeout
case when Bluetooth state changes from Turning On to Off.

Root cause: Setting Bluetooth Persist state to handle the
enable timeout case so that Bluetooth doesnot self enable
after enable timeout case is handled.

Fix: Setting the Bluetooth Persist State to Off when enable
timeout occurs.
