[ Upstream commit 1bc2b7bfba6e2f64edf5e246f3af2967261f6c3d ]
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.
Fixes: 349e7a85b25f ("PCI: endpoint: functions: Add an EP function to test PCI")
