Currently, when a notifier is attempted to be registered and its flags are not supported (especially the MAP one) by the IOMMU MR, we generally abruptly exit in the IOMMU code. The failure could be handled more nicely in the caller and especially in the VFIO code. So let's allow memory_region_register_iommu_notifier() to fail as well as notify_flag_changed() callback. All sites implementing the callback are updated. This patch does not yet remove the exit(1) in the amd_iommu code. in SMMUv3 we turn the warning message into an error message saying that the assigned device would not work properly.
