Lu Baolu bfd3c6b9fa iommu/vt-d: Allow zero SAGAW if second-stage not supported 
The VT-d spec states (in section 11.4.2) that hardware implementations
reporting second-stage translation support (SSTS) field as Clear also
report the SAGAW field as 0. Fix an inappropriate check in alloc_iommu().

Fixes: 792fb43ce2 ("iommu/vt-d: Enable Intel IOMMU scalable mode by default")
