John Sperbeck a557ae0942 iommu/amd: use full 64-bit value in build_completion_wait() ...

[ Upstream commit 94a568ce32038d8ff9257004bb4632e60eb43a49 ]

We started using a 64 bit completion value.  Unfortunately, we only
stored the low 32-bits, so a very large completion value would never
be matched in iommu_completion_wait().
