Johan Hovold 32a4bf2e81 USB: console: fix potential use after free ...

Use tty kref to release the fake tty in usb_console_setup to avoid use
after free if the underlying serial driver has acquired a reference.

Note that using the tty destructor release_one_tty requires some more
state to be initialised.
