Currently, s390x-pci performs accounting against the vfio DMA limit and triggers the guest to clean up mappings when the limit is reached. Let's go a step further and also limit the size of the supported DMA aperture reported to the guest based upon the initial vfio DMA limit reported for the container (if less than than the size reported by the firmware/host zPCI layer). This avoids processing sections of the guest DMA table during global refresh that, for common use cases, will never be used anway, and makes exhausting the vfio DMA limit due to mismatch between guest aperture size and host limit far less likely and more indicitive of an error.
