IB/mlx4: Fix check of max_qp_dest_rdma in modify QP
max_qp_dest_rdma is already in natural units - no need to shift. This was discovered by a test that deliberately requests more outstanding atomic operation than the device supports. Found by Sagi Rotem at Mellanox. Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
