Subject: usb: cdns3: remove redundant assignment to ret on error exit path

usb: cdns3: remove redundant assignment to ret on error exit path

In the case where an allocation fails for priv_ep ret is
assigned -ENOMEM and the code exits via the exit path 'err'.
The exit path returns -ENOMEM without using variable ret, so
the assingment is redundant and can be removed.
