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

Browse source 
[ Upstream commit 1bc2b7bfba ]

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: 349e7a85b2 ("PCI: endpoint: functions: Add an EP function to test PCI")
