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

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.
