Sometimes, on removal SDL_EVDEV_udev_callback() gets called with zero udev_class. This in turn seems to be caused the SDL_udev.c:guess_device_class() failing to find the attributes of the parent device. Apparently this is normal, attributes are not guaranteed to be in place during removal, depending on timing. This lack of attributes causes guess_device_class() to return zero. This fix mimics the code in linux/SDL_sysjoystick.c:joystick_udev_callback() which effectively has the same fix already in place.
