iommu/vt-d: Use struct_size() helper
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, replace code of the following form:
size = sizeof(*info) + level * sizeof(info->path[0]);
with:
size = struct_size(info, path, level);
