gpio: ftgpio010: Do not check for 0 return after calling platform_get_irq() 



Since commit a85a6c86 ("driver core: platform: Clarify that IRQ 0
is invalid"), there is no possible for platform_get_irq() to return 0.

And the return value of platform_get_irq() is more sensible
to show the error reason.
