memory: fsl-corenet-cf: Fix handling of platform_get_irq() error
[ Upstream commit dd85345abca60a8916617e8d75c0f9ce334336dd ]
platform_get_irq() returns -ERRNO on error. In such case comparison
to 0 would pass the check.
Fixes: 54afbec0d57f ("memory: Freescale CoreNet Coherency Fabric error reporting driver")
