iommu/vt-d: Fix memory leak in intel_iommu_put_resv_regions()
Commit 9d3a4de4cb8d ("iommu: Disambiguate MSI region types") changed
the reserved region type in intel_iommu_get_resv_regions() from
IOMMU_RESV_RESERVED to IOMMU_RESV_MSI, but it forgot to also change
the type in intel_iommu_put_resv_regions().
This leads to a memory leak, because now the check in
intel_iommu_put_resv_regions() for IOMMU_RESV_RESERVED will never
be true, and no allocated regions will be freed.
Fix this by changing the region type in intel_iommu_put_resv_regions()
to IOMMU_RESV_MSI, matching the type of the allocated regions.
