net: usb: set error code when usb_alloc_urb fails
In function lan78xx_probe(), variable ret takes the errno code on failures. However, when the call to usb_alloc_urb() fails, its value will keeps 0. 0 indicates success in the context, which is inconsistent with the execution result. This patch fixes the bug, assigning "-ENOMEM" to ret when usb_alloc_urb() returns a NULL pointer.
