memory: fsl-corenet-cf: Fix handling of platform_get_irq() error
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") Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20200827073315.29351-1-krzk@kernel.org
