[ Upstream commit 0b7a04a30eef20e6b24926a45c0ce7906ae85bd6 ]
After commit bda324fd037a ("vdpasim: control virtqueue support"),
vdpasim->iommu became an array of IOTLB, so we should clean the
mappings of each free one by one instead of just deleting the ranges
in the first IOTLB which may leak maps.
