[Qemu-devel] [RFC v5 22/22] hw/vfio/common: Do not print error when viommu translates into an mmio region

[Eric Auger <eric.auger@redhat.com>]

On ARM, the MSI doorbell is translated by the virtual IOMMU.
As such address_space_translate() returns the MSI controller
MMIO region and we get an "iommu map to non memory area"
message. Let's remove this latter.
