Mixing these together is just a mess, make a dedicated version, mlx5_ib_update_mr_pas(), which directly loads the whole MTT for a non-ODP MR. The split out version can trivially use a simple loop with rdma_for_each_block() which allows using the core code to compute the MR pages and avoids seeking in the SGL list after each chunk as the __mlx5_ib_populate_pas() call required. Significantly speeds loading large MTTs.
