usb: gadget: network: fix bind() error path
commit e79cc615a9bb44da72c499ccfa2c9c4bbea3aa84 upstream.
I think this is wrong since 72c973dd ("usb: gadget: add
usb_endpoint_descriptor to struct usb_ep"). If we fail to allocate an ep
or bail out early we shouldn't check for the descriptor which is
assigned at ep_enable() time.
