mlx5_core: Store MR attributes in mlx5_mr_core during creation and after UMR
The patch stores iova, pd and size during mr creation and after UMRs that modify them. It removes the unused access flags field. Signed-off-by: Haggai Eran <haggaie@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
