PCI: endpoint: Don't stop controller when unbinding endpoint function 

Unbinding an endpoint function from the endpoint controller shouldn't stop
the controller.  This is especially a problem for multi-function endpoints
where other endpoints may still be active.

Don't stop the controller when unbinding one of its endpoints.  Normally
the controller is stopped via configfs.
