usbip: vhci_hcd: only return urb at enqueue when served 

We handle USB_REQ_SET_ADDRESS at enqueue, so we want to perform
cleanup and giveback the urb. We should not call usb_hcd_giveback_urb
when we're cleaning up after a failed enqueue, though.

Only giveback the urb at cleanup when we claim to have served it.
