    conf: Remove dead code
    
    The switch in virDomainPCIControllerModelToConnectType()
    had some code that, while techically part of the
    _PCIE_SWITCH_DOWNSTREAM_PORT case, was in fact dead due
    to the early return.
    
    Get rid of the dead code, and fix the inaccurate function
    description while at it.
