iommu/arm-smmu: Tighten up global fault reporting On systems which use a single, combined irq line for the SMMU, context faults may result in us spuriously reporting global faults with zero status registers. This patch fixes up the fsr checks in both the context and global fault interrupt handlers, so that we only report the fault if the fsr indicates something did indeed go awry.
