backlight: l4f00242t03: fix error handling in l4f00242t03_probe
Error handling fixes: 1. In the case of kzalloc failure, simple return -ENOMEM instead of goto err. ( priv is NULL in this case ) 2. In the case of gpio_request fail for reset_gpio and data_enable_gpio, properly release resources by goto err and err2 respectively.
