mtd: rawnand: vf610_nfc: Do not check 0 for platform_get_irq()

Since platform_get_irq() never returned zero, so it need not to check
whether it returned zero, and we use the return error code of
platform_get_irq() to replace the current return error code, for that
platform_get_irq() may return -EINVAL or -ENXIO.
