MLK-22527-1 usb: cdns3: gadget: quit functional halt if there are pending requests

If the non-control endpoints want to halt, but there are pending
requests on this endpoint, we need to return -EAGAIN, otherwise,
the controller may be in stuck if we stall the doolbell'ed
endpoint.

With this change, we could pass the USB certification MSC test.
