iommu_pt: Fix pgsize_bitmap calculation in get_info for smaller vasz's

Browse source

To properly enforce the domain VA limit, clamp pgsize_bitmap using the
requested max_vasz_lg2 in get_info().
Apply the same VA limit as get_info() in the kunit possible_sizes test so
assertions stay consistent with the domain bitmap.
