From: Hawking Zhang <[email protected]> gmc v12_1 currently derives the number of mmhub vmhubs from the aid_mask when populating vmhubs_mask. This breaks when mmhub is represented by mid and mmhub inst_mask does not match the aid_mask. Iterate over adev->mmhub.inst_mask instead so vmhubs_mask reflects the discovered mmhub instances.
