[PATCH] tipar oops fix 

If compiled into the kernel, parport_register_driver() is called before the
parport driver has been initalised.

This means that it is expected that tp_count is 0 after the
parport_register_driver() call() - tipar's attach function will not be
called until later during bootup.
