Miaoqian Lin 7207e12d24 slimbus: qcom: Fix IRQ check in qcom_slim_probe

commit fe503887ee upstream.

platform_get_irq() returns non-zero IRQ number on success,
negative error number 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.
