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().
Fixes: c69d89aff393 ("iommu/amd: Use 4K page for completion wait write-back semaphore")
