iommu/vt-d: Really use upper context table when necessary

commit 4df4eab168c1c4058603be55a3169d4a45779cc0 upstream.

There is a bug in iommu_context_addr() which will always use
the lower context table, even when the upper context table
needs to be used. Fix this issue.

Fixes: 03ecc32c5274 ("iommu/vt-d: support extended root and context entries")
