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.
