usb: gadget: net2272: Fix net2272_dequeue()
Restore the status of ep->stopped in function net2272_dequeue(). When the given request is not found in the endpoint queue the function returns -EINVAL without restoring the state of ep->stopped. Thus the endpoint keeps blocked and does not transfer any data anymore. This fix is only compile-tested, since we do not have a corresponding hardware. An analogous fix was tested in the sibling driver.
