    Bluetooth: mgmt: Fix limited discoverable off timeout
    
    [ Upstream commit 0bd1fb586235224048c726922db048d1bce6354a ]
    
    LIMITED_DISCOVERABLE flag is not reset from Class of Device and
    advertisement on limited discoverable timeout. This prevents to pass PTS
    test GAP/DISC/LIMM/BV-02-C
    
    Calling set_discoverable_sync as when the limited discovery is set
    correctly update the Class of Device and advertisement.
