lib82596: Fix IRQ check in sni_82596_probe
commit 99218cbf81bf21355a3de61cd46a706d36e900e6 upstream. platform_get_irq() returns negative error number instead 0 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.
