USB: legousbtower: fix use-after-free on release
The driver was accessing its struct usb_device 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: fef526cae700 ("USB: legousbtower: remove custom debug macro")
