intel_iommu: Correct caching-mode error message
If we try to use the intel-iommu device with vfio-pci devices without
caching mode enabled, we're told:
qemu-system-x86_64: We need to set caching-mode=1 for intel-iommu to enable
device assignment with IOMMU protection.
But to enable caching mode, the option is actually "caching-mode=on".
