watchdog: ftwdt010_wdt: fix test for platform_get_irq() failure
This code assumes that platform_get_irq() function returns zero on
failure. In fact, platform_get_irq() never returns zero. It returns
negative error codes or positive non-zero values on success.
Fixes: eca10ae6000d ("watchdog: add driver for Cortina Gemini watchdog")
