Bluetooth: Handle user switch with new states

When user switch occurs, BT is toggled. However since the state
change callbacks are disabled, state never moves forward from
STATE_BLE_ON. This causes toggle timeout, causing recovery.
This change handles the case by manually causing the state
change handling during the wait period.
