spi: fsl-spi: 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.
