While the 2nd of the commits referenced below should have moved the call
to amd_iommu_msi_enable() instead of adding another one, the situation
wasn't quite right even before: It can't have done any good to enable
MSI when no IRQ was allocated for it, yet.
Fixes: 5f569f1ac50e ("AMD/IOMMU: allow enabling with IRQ not yet set up")
Fixes: d9e49d1afe2e ("AMD/IOMMU: adjust setup of internal interrupt for x2APIC
mode")
