USB: iowarrior: fix use-after-free on release
commit 80cd5479b525093a56ef768553045741af61b250 upstream.
The driver was accessing its struct usb_interface from its release()
callback without holding a reference. This would lead to a
use-after-free whenever debugging was enabled and the device was
disconnected while its character device was open.
