usb: gadget: dummy_hcd: Reject hub port requests for non-existent ports
The `dummy_hub_control()` function handles USB hub class requests
to the virtual root hub. The `GetPortStatus` case returns -EPIPE for
requests with `wIndex != 1`, since the virtual root hub has only a
single port. However, the `ClearPortFeature` and `SetPortFeature`
cases lack the same check.
Fix this by extending the `wIndex != 1` rejection to both cases,
matching the existing behavior of `GetPortStatus`.
