Jason Gunthorpe e5a4b227bc iommufd: Make vfio_compat's unmap succeed if the range is already empty ...

[ Upstream commit afb47765f9235181fddc61c8633b5a8cfae29fd2 ]

iommufd returns ENOENT when attempting to unmap a range that is already
empty, while vfio type1 returns success. Fix vfio_compat to match.
