    rdp-server: Tear down NVENC after sessions
    
    Sessions borrow the NVENC instance from the server; if we tear it down
    before tearing down the sessions, they may crash as it disappeared under
    their feet.
    
    Fix this by destroying the NVENC subsystem after the sessions when
    disabling the RDP server.
