USB: chaoskey: fix use-after-free on release
commit 93ddb1f56ae102f14f9e46a9a9c8017faa970003 upstream.
The driver was accessing its struct usb_interface in its release()
callback without holding a reference. This would lead to a
use-after-free whenever the device was disconnected while the character
device was still open.
Fixes: 66e3e591891d ("usb: Add driver for Altus Metrum ChaosKey device (v2)")
