Subject: USB: serial: console: fix use-after-free after failed setup

From: Johan Hovold <[email protected]>

commit 299d7572e46f98534033a9e65973f13ad1ce9047 upstream.

Make sure to reset the USB-console port pointer when console setup fails in order to avoid having the struct usb_serial be prematurely freed by the console code when the device is later disconnected.
