[PATCH] USB: serial: bus: fix const issue in usb_serial_device_match()

usb_serial_device_match() takes a const pointer, and then decides to
cast it away into a non-const one, which is not a good thing to do
overall. Fix this up by properly setting the pointers to be const to
preserve that attribute.
