[PATCH] gpio: loongson-64bit: Fix NULL check after devm_kcalloc() in loongson_gpio_init_irqchip()

[Chen Ni]

Fix incorrect NULL check in loongson_gpio_init_irqchip().
The function checks chip->parent instead of chip->irq.parents.

Fixes: 03c146cb6cd1 ("gpio: loongson-64bit: Add support for Loongson-2K0300 SoC")
