[Qemu-arm] [PATCH RFC v5 1/5] hw/vfio/common: Do not print error when viommu translates into an mmio region

[Bharat Bhushan]

From: Eric Auger <address@hidden>

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.
