USB: console: fix potential use after free
commit 32a4bf2e81ec378e5925d4e069e0677a6c86a6ad upstream.
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.
Fixes: 4a90f09b20f4 ("tty: usb-serial krefs")
