usb: iowarrior: remove inherent race with minor number

The driver saves the minor number it gets upon registration
in its descriptor for debugging purposes. However, there is
inevitably a window between registration and saving the correct
minor in a descriptor. During this window the debugging output
will be wrong.
As wrong debug output is worse than no debug output, just
remove it.
