Rob Bradford 59f9c7c08a virtio-devices: iommu: Cap mappings per domain ...

Domain::mappings only shrinks on UNMAP. Without a bound a guest can
issue MAP for arbitrarily many distinct virt_start values and drive
the VMM heap until the host runs out.

Reject MAP with VIRTIO_IOMMU_S_NOMEM at 1M entries per domain.
