gpio: idt3243x: Fix IRQ check in idt_gpio_probe
commit 30fee1d7462a446ade399c0819717a830cbdca69 upstream.
platform_get_irq() returns negative error number instead 0 on failure.
And the doc of platform_get_irq() provides a usage example:
int irq = platform_get_irq(pdev, 0);
if (irq < 0)
return irq;
Fix the check of return value to catch errors correctly.
