iommu/amd: Finish TLB flush in amd_iommu_unmap()
commit ce76353f169a6471542d999baf3d29b121dce9c0 upstream.
The function only sends the flush command to the IOMMU(s),
but does not wait for its completion when it returns. Fix
that.
Fixes: 601367d76bd1 ('x86/amd-iommu: Remove iommu_flush_domain function')
