USB: legousbtower: fix use-after-free on release
commit 726b55d0e22ca72c69c947af87785c830289ddbc upstream.
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.
