zorro: make match function take a const pointer

In commit d69d804 ("driver core: have match() callback in struct
bus_type take a const *"), the match callback for busses was changed to
take a const pointer to struct device_driver.  Unfortunately I missed
fixing up the zorro code, and was only noticed after-the-fact by the
kernel test robot.  Resolve this issue by properly changing the
zorro_bus_match() function.
